THEN AND NOW: Reality TV's most iconic couples

From the first minute Pratt appeared on "The Hills" and established himself as a villain, it was impossible to look away. Pratt and Montag's relationship became the main source of drama, as he came between Montag and her best friend Lauren Conrad, and constantly feuded with his sister Stephanie.

The two got hitched in April 2009 — of course, it was caught on camera — and remained on the show almost to the bitter end.

After that, they appeared on various other reality shows, including "I'm a Celebrity... Get Me Out of Here!" "Celebrity Big Brother," "Marriage Bootcamp," and "Celebrity Wife Swap."

The Pratts were featured in "The Hills: New Beginnings" reboot in 2019, which showcased the two of them dealing with parenthood and debating if they wanted to have another child. A second season was renewed, but there haven't been any updates yet.

Pratt also has a crystal business, as well as a thriving social media presence.

When "KUWTK" premiered, Kardashian had been dating Disick for a few months. The two experienced high highs and low lows — they have three kids together, but were also dealing with Disick's sobriety, the death of both of his parents, his fights with her family, a fair number of failed proposals, and more than one cheating scandal.

The two called it quits for good in 2015.

Although they're not together, Disick has remained an integral part of both "KUWTK" and the KarJenner clan — he truly is part of the family.

Both Kardashian and Disick have dated other people in the five years since their break-up, but they are both currently single. So, there's no telling what will happen next, especially after the show airs its final episode in 2021.

Tamburello, at the time, was most famous for his appearance on "The Real World: Paris," while Brown had appeared in the first "Real World/Road Rules Challenge: Fresh Meat" season in 2006. They met on 2006's "The Duel."

Throughout the season, as Brown was battling ovarian cancer, viewers got to see a softer side of Tamburello as he supported her, and eventually had one of the sweetest first kisses in "Challenge" history.

Throughout the rest of their appearances, Brown and Tamburello at the least always had affection for each other — and at most, they were fully dating. Their last season together was "The Challenge: Battle of the Exes II" which aired in 2015, and they didn't end on the best terms.

Brown was medically disqualified from her last season of "The Challenge," as she was deemed too sick to compete.

Although the two were not together when she died, they were close. According to People, "Diem had such a big heart that she had room to love a lot of people, and he was one of them," said her longtime friend Alicia Quarles. In a since-deleted Instagram, Tamburello wrote, "You have always been My Angel … We've been thru so much together over the years … Our plan to be together hasn't changed … it's just going to take a little longer now."

Tamburello married his now-wife Lilianet Solares in 2018. They have one son together. The wedding was documented in the MTV special "The Challenge: CT's Getting Married."

Right from the very beginning of the show, which focused on Jon, Kate, their set of twins, and their set of sextuplets, audiences watched the slow demise of Jon and Kate, who barely seemed to like each other.

By 2009, their show was hitting ratings highs, while their marriage was falling apart. They announced their divorce that year, and things quickly got messy. There were allegations of Jon partying with college students, cheating, and abandoning his family, which he denied. Vanity Fair even called them "the biggest celebrity story of the year" in 2009.

As their relationship continued to break down on the show, TLC announced that Jon would be taken out, and it was now going to be called "Kate Plus 8." It has filmed sporadically over the last few years.

Though it's been a decade since their divorce, things still aren't great. Jon has custody of two of his kids, while Kate has the other six — apparently the two factions of siblings don't speak, either.

Rehn became the first-ever "Bachelorette" lead in 2003 after she had her heart broken on the first season of "The Bachelor," starring Alex Michel.

From the very beginning, it was clear that Rehn and Sutter had a special bond. Rehn chose Sutter in the finale, and he proposed. Their wedding was televised (the first of the franchise) and shown as a miniseries called "Trista and Ryan's Wedding" in December 2003.

They've appeared sporadically on reality TV since. Rehn appeared on the first season of "Dancing with the Stars," and the couple appeared on "Marriage Boot Camp" in 2014. They're still married, live in Colorado, and have two kids, Max and Blakesley.

The two met on "Survivor: All-Stars," which premiered in 2004. They quickly established an alliance and made it all the way to the end. But before Brkich could be crowned Sole Survivor, Mariano got down on one knee and proposed.

In 2005, the two starred in their own special "Rob and Amber Get Married."

The couple has competed on "Amazing Race" twice and, more recently, they competed on season 40's "Survivor: Winners at War."

They have four daughters.

Carmelo is an NBA star, La La was a frequent host on both MTV and VH1 reality TV shows — creating a show based on their wedding was a no-brainer. "La La's Full Court Wedding" aired in 2010, and created enough of a buzz that the couple received another show "La La's Full Court Life," which aired for five seasons from 2011 to 2014.

The two first split in 2017, as TMZ reported they were living separately amidst rumors of infidelity. The Anthonys then seemed to be on the road to reconciliation in 2018, but when Carmelo was seen on a yacht with another woman, all reconciliation talks seemed to halt.

However, the couple is living together with their son amidst the pandemic, and they are still legally married so perhaps a more permanent reconciliation is in their future.

When the "Real Housewives of Beverly Hills" spin-off premiered in 2013, Taylor and Schroeder claimed to be the glue holding their friend group together, and had been living together for over a year. As the first two seasons progressed, Schroeder became convinced Taylor had first cheated on her in Las Vegas, which he admitted, and then that he had slept with her best friend Kristen Doute (who happened to be dating Taylor's close friend Tom Sandoval, as well). Doute and Taylor eventually both admitted to that as well.

This all led to Schroeder leaving the show for a period, as she said she couldn't stand to be around Taylor.

It's almost mind-boggling to see these two in the same room together, still. But both of them have put their differences aside and have somehow become close friends. Schroeder is close with Taylor's wife, Brittany Cartwright — Schroeder was even a bridesmaid — while Taylor is close with Schroeder's husband, Beau Clark.

Schroeder was fired from "Vanderpump" in 2020 over racist remarks and behaviors, including a comment she made on a podcast that resurfaced amidst the George Floyd protests. Taylor and Cartwright technically are still on the show, but it's been put on hold due to the pandemic.

"Newlyweds" was one of the first mega-hit reality TV shows, and one of the first reality shows to focus on people who were already celebrities. Lachey was part of 98 Degrees, while Simpson was a singer, as well.

The show, which aired on "MTV," focused on Simpson and Lachey's first few years of married life. Simpson's confusion over whether she was eating tuna or chicken (because the can was labeled "Chicken of the Sea") remains iconic.

It aired for three seasons, from 2003 to March 2005. They announced their divorce in December of that year.

Lachey is now married to Vanessa Minnillo, a former "TRL" host. They've been together since 2006, when they met on the set of one of Lachey's music videos. They briefly called it quits in 2009, but got back together a few months later. They were married in 2010, and have three kids together. Most recently, they co-hosted Netflix reality sensation "Love Is Blind."

Simpson is also married with three kids, to former NFL player Eric Johnson. They got engaged in 2010. Before Johnson, Simpson also publicly dated John Mayer and Tony Romo.

This year, Simpson released her memoir "Open Book," which detailed her relationship with Lachey, her struggles with alcoholism, and other traumatic experiences from her childhood.

From the very first "Raaaahn," fans of reality TV knew that they were witnessing the formation of one of the most iconic couples in the genre's history. For all six seasons of "Jersey Shore," viewers watched as Giancola and Ortiz-Magro tried to stay away from each other ... or proclaim their undying love for each other.

Though their relationship clearly caused a lot of stress and pain to both, it made for riveting TV — and the way the rest of their cast-members reacted to their relationship also made for unforgettable moments. We will never forget Snooki and JWoww's note to Giancola about her boyfriend's antics at Bed.

The two ended their relationship for good not long after "Jersey Shore" ended. Giancola didn't return for "Family Vacation," though she was mentioned frequently, as Ortiz-Magro claimed he wasn't over his ex. For her part, Giancola has been engaged to longtime boyfriend Christian Biscardi since 2019.

Ortiz-Magro's relationship with Jen Farley, his now-ex and mother of his child, has been shown on "Family Vacation."

Nene and Gregg had been together since the late '90s when she joined "RHOA" in 2008. For her first few seasons, viewers watched as their marriage fell apart — specifically in season three, when Gregg vented about their relationship on a radio show, and NeNe met with a divorce lawyer. They split up in 2011.

Their divorce was short-lived — the couple got engaged again on January 1, 2013. They were remarried that June, which was documented on "I Dream of NeNe: The Wedding."

When Gregg was diagnosed with stage 3 colon cancer in 2018, the two weren't in a great place, but NeNe stuck by her husband. By 2019, he was cancer-free.
