Heidi Montag and Spencer Pratt have been together for 14 years. Here's a timeline of their relationship.

Montag and Pratt met at a club called Privilege in Hollywood while Montag was filming "The Hills."

Pratt had gone there with his friend, Brody Jenner, looking for a way to get a role on the reality show.

Montag later told Vice in 2016 that she knew when she met him that he was the one.

"I pretty much told everyone I was going to marry him and that I loved him. [Everyone] thought I was crazy," she said.

Lauren Conrad didn't like Pratt or Montag's relationship with him.

After many heated arguments, on the first episode of season three of "The Hills," Conrad accused them of circulating rumors that she had a sex tape with Jason Wahler.

Montag then moved out of their apartment, and the women ended their friendship.

On a trip to Santa Barbara, MTV cameras caught Pratt proposing to Montag while they were on the beach.

They told Cosmopolitan in 2016 that it was actually a promise ring that Montag picked out, not an engagement ring.

"... They kinda like jacked it from us and turned a promise ring scene into an engagement ring, and it kind of snowballed from there," Pratt said. "Technically, that was a promise ring."

During a trip to Cabo San Lucas, Mexico, Pratt and Montag decided to elope.

"I was just putting it out there, how easy it would be with no drama," Pratt told Us Weekly. "It was exactly the wedding I wanted."

But, according to MTV News, many questioned the legality of the marriage.

"Like other elopements that happen outside the country, we'll take care of the legal details when we get home," Pratt said at the time.

When a clip from "The Hills" showed Montag and Pratt getting married in a courthouse, many people wondered if the two had actually eloped at all.

According to People, Pratt addressed the controversy on KISS-FM's "On Air With Ryan Seacrest."

"We checked the confidentiality box, so good luck people," he said, speaking of those trying to dig into their legal relationship status.

A few months later, the couple made it official.

They got married at the Westminster Presbyterian Church in Pasadena, California, in front of 200 guests and MTV cameras.

The wedding later appeared on season five, episode 10 of "The Hills."

In the summer of 2009, the couple branched out to try another reality show, NBC's "I'm a Celebrity ... Get Me Out of Here!"

But they refused to do a challenge, fought with almost all of their camp mates, and then promptly quit the competition.

They ended up returning, but then they left the show again when Montag got sick and had to go to the hospital.

In 2010, Montag appeared on the cover of People magazine after undergoing 10 different plastic-surgery procedures in one day in late 2009.

Although many were shocked by her transformation and some felt she went too far, she defended her decision.

"For the past three years, I've thought about what to have done," she told the publication. "I'm beyond obsessed."

Although Pratt had been Montag's manager since soon after they met, Montag fired him from the role in March 2010.

She told People magazine that she hired a psychic, Aiden Chase, to replace him.

"The time for change is now. Never mix business and pleasure," she told the publication. "We are no longer Speidi but Spencer and Heidi."

Later that month, Pratt released a statement to People saying he was taking a break from the reality show to pursue work in the cybersecurity division of American Defense Enterprises.

Montag, however, would be remaining on the show.

Later, a source told Us Weekly that Pratt had actually been suspended from the show after he reportedly threatened a producer.

"All of that stuff about him leaving 'The Hills' to fight cyber crime is not true," the source said. "...The show agreed that Spencer would leave 'The Hills' for six weeks to do anger management training once a week at home. If he completes it, he can return to the show."

Montag's role was also reportedly reduced after she said she didn't want to do a fake divorce storyline.

Pratt told the Daily Beast in 2011 that his fight with the producer started because he said she was trying to push his sister Stephanie's drug and alcohol problem to rock bottom.

"To the point when I said — and this is when the producers got scared of me — 'You want me to punch my sister in the face? Are you trying to get me to kill you?' I didn't say, 'I'm killing you.' If I did, MTV would have had me arrested," he said.

After saying she needed to be alone for a while, Montag made the move to file for a legal separation from Pratt, citing irreconcilable differences, according to People.

She told People magazine she'd already moved out of their home.

"There are so many lies out there about me and I just needed space – even away from my husband," she said.

Several weeks later, Montag amended her petition for separation and filed for divorce from her husband.

He responded to this news by telling People that their marriage had been fake.

"I love Heidi but our marriage was a show — it was part of 'The Hills' world," he said. "And that world is on a sound stage."

He continued, "Some say if you can't handle the heat get out of the kitchen, Well, Heidi couldn't handle King Spencer's fame so she got out of the marriage."

In the midst of their divorce proceedings, Pratt told Us Weekly he was going to sell a sex tape featuring Montag.

"I've been making films since I was in the seventh grade," he said. "I'm looking forward to people seeing my directorial debut!"

At the time, Steve Hirsch, co-CEO of porn company Vivid Entertainment, told TMZ, "We are in early negotiations to possibly come to terms for a deal."

By September, Pratt publicly apologized to Montag, and the two went on a long vacation to Costa Rica.

When they returned, they told People they decided to try and make things work.

"We are back together trying to make things work," the couple told the publication in a joint statement. "Costa Rica really put things in perspective. We do love each other and realized we do want to spend the rest of our lives together."

The two renewed their vows at a beachfront house in Carpinteria, California.

Per People, Pratt told Entertainment Tonight, "Last time it was about everything else, it was about drama, it was about ratings."

Montag continued, "It was about everyone but us, so this is really our first wedding about Spencer and I and our love."

During an interview with the Daily Beast, the couple revealed their entire breakup and divorce had been fake, and that they were using it as a ploy to make money because they were broke.

When asked if they ever broke up their response was, "Not for one minute."

"We got so deep with how many storylines we had to do to continue the machine," Pratt added.

To which Montag asked, "So what was one more fake breakup?"

"At that point, we were pulling our last cards," Pratt said. "We felt the hot-air balloon losing its gas. And at that stage, our income would be selling the photo that would go along with the divorce."

After a few stints on shows like "Celebrity Big Brother" and "The View," Speidi returned to reality television for WE TV's "Marriage Boot Camp: Reality Stars."

When the reports first circulated, Montag and Pratt denied their involvement in Conrad's sex-tape scandal. But years later, Pratt told Complex he was behind the rumors.

He also maintained that the sex tape exists.

"Lauren is a cold-hearted killer. That's what people don't get. She will cut you in your sleep," Pratt said. "She tried to destroy us. If you want to throw missiles, I'm throwing a nuke. This is how I operate."

Although they were each making six figures for their roles on "The Hills," paparazzi shoots and paid appearances, and other reality show appearances, the couple told People that they spent all of their money.

"I was kind of playing house," Montag said. "I felt like I was someone I wasn't. We had business managers who told us to stop spending but we acted like we knew what we were doing."

After causing a lot of arguments the first time around, Speidi secured a spot on the "All Stars vs New Stars" line-up of the UK's Channel 5 reality show.

Sources confirmed to People that Montag was pregnant with the couple's first child.

The news came after she said they were looking forward to having kids.

"I had to pray to get my husband to even … agree to have a kid," Montag said.

Montag gave birth to their first child, a son named Gunner Stone, in early October.

"We are so blessed to have a beautiful healthy baby boy," she told Us Weekly. "It was the hardest and most rewarding experience."

Pratt added, "Officially the most lit day of my life."

When speaking to E! News about having more kids, Pratt and Montag said they were definitely thinking about doing it soon.

"A psychic did tell us we're going to have twins, so uh-oh, watch out Mary-Kate and Ashley," Pratt said.

MTV announced that they were going to bring back "The Hills" with most of the original cast, including Speidi.

In the summer of 2019, many of the early-2000s reality-TV stars reunited for the reboot of "The Hills," including Pratt and Montag.

Conrad didn't return for the new series.

Pratt told Entertainment Tonight that MTV was working on finding a way to film season two of "The Hills: New Beginnings" amid the coronavirus pandemic.

"Before the quarantine, 'The Hills' became the best show ever," he said. "... So, it's kinda frustrating. ... Once when we all get out of this, everyone will be so turnt up to go out that everyone's emotions will keep going, but, it was really good before we got locked up."

Montag and Pratt both took to Instagram to celebrate their 12th wedding anniversary.

Part of Montag's caption read, "14 years has flown by together ... Our love transcends time."

And part of Pratt's post read, "What an incredible journey it's been! My only regret is not proposing to you the night we met two years before this photo was taken! Should be 14 years today."

In February, reports that Montag was pregnant again started circulating, but she shut those down with a tweet that read, "No I am not pregnant yet. Just a little overweight."

In early May, Pratt also told Us Weekly that he and Montag were on "different pages" about trying to have a kid during the coronavirus pandemic.

"Heidi was willing to [get] pregnant during the pandemic … And I was, like, hearing stories about dads having to wait outside of the building. They'd come in for, like, two minutes ... " he said. "I didn't want to do that. It felt like a sci-fi movie."

But during a May appearance on PeopleTV's "Reality Check," the couple said they're actively trying for another baby.

"No spoiler alerts but no baby yet," Pratt said. "That is the struggle in real life, reality."
