Justin Theroux says he and Jennifer Aniston 'still bring each other joy' 3 years after their split. Here's a timeline of their relationship.

Theroux co-wrote the screenplay and story for the 2008 comedy, which starred Ben Stiller, Jack Black, and Robert Downey Jr.

Aniston is close friends with Stiller, which explains why she visited the set. Stiller also guest-starred on an episode of "Friends" during season three and played Aniston's on-screen boyfriend.

The exact time in 2011 when they started dating is unclear. According to People, the two actors rented a home in the Hollywood Hills in August.

Aniston is known for her role as Rachel Green on "Friends," which earned her a Golden Globe win in 2003.

Theroux looked nearly unrecognizable in the movie, with long, wavy locks and facial hair.

"I do my own facial-hair stunts, and that beard was intense, its own being," Theroux said of his character, Seth, during an interview with New York magazine.

Even though Aniston and Theroux had scenes together in "Wanderlust," their characters weren't love interests.

At the time, Theroux was also in a relationship with stylist Heidi Bivens, and they were together for 14 years before they split in 2011. It was speculated that he fell in love with Aniston while he was still in a relationship with Bivens.

During an interview with Popsugar, Aniston elaborated on her first meeting with Theroux, and what she initially thought of him.

"I met Justin five years ago and he was always so sweet, very nice," Aniston said.

She added: "First you think, 'Oh, he could be a serial killer,' but the nicest person in the world."

Aniston also admitted that at the camera test for "Wanderlust," she didn't recognize Theroux at first, because he "disappears" and transforms himself when playing different roles.

Aniston got real about relationships in her cover story.

"Having experienced everything you don't want in a partner over time, it starts to narrow down to what you actually do want," she said during the interview. "As I get older, I realize what qualities are important in love and what suits me. And what I won't settle for."

The couple tied the knot days before Theroux's 44th birthday at their California home. The secret ceremony had a small crowd that included guests like Ellen DeGeneres and Jimmy Kimmel.

In an interview two years later, Theroux said that he liked having a small ceremony.

"It's so much more special when it's just your closest friends and family and it's lovely," he told Entertainment Tonight. "[Aniston and I] wanted it to be a peaceful environment, you don't want it to be hectic."

Frustrated with the speculation on whether or not she was pregnant, Aniston wrote an essay for Huffington Post.

"The sheer amount of resources being spent right now by press trying to simply uncover whether or not I am pregnant (for the bajillionth time ... but who's counting) points to the perpetuation of this notion that women are somehow incomplete, unsuccessful, or unhappy if they're not married with children," she said.

Theroux then called Aniston his "Woman Crush Wednesday" on Instagram and said that her essay was one of the reasons why he adores her.

In another interview a few months later, Theroux called Aniston a "badass."

"She has lived through a lot of bulls---," he said during an interview with Sunday Times. "Many people would have crumbled under some of the stresses that have been put on her. I'm very proud of her for that, for the way she handles herself. So in a weird way, it's an honor to stand behind her. Truly, in that sense, she's amazing."

Talking to "Entertainment Tonight," Theroux said that the key is actually not complicated.

"We appreciate each other's sense of humor, we respect one another, and we get along," he said. "I know it sounds simple but it's true!"

They were joined by Courteney Cox and fiancé Johnny McDaid.

Aniston wore a stunning, black Versace dress at the event.

"Marriage makes the small things much smaller and the big things small," he said during an interview with Rhapsody magazine. "You have an ally. It's good to have someone have your back."

The premiere took place in California.

He captioned the photo "In Louvre," and Theroux and Aniston seemed to be having a fun time sightseeing in France.

They were in attendance as Jason Bateman received a star on the Hollywood Walk of Fame.

During an interview with Elle, Aniston spoke about her relationship with Theroux, and revealed how he slept through an audition for "Friends."

"Oh, it was perfect when we met — perfect," she said "And he didn't sleep through it! He just didn't want to get on a plane. He didn't he didn't want to live in California at that point. He was a total New Yorker, and he wasn't moving."

Reportedly, Theroux's position as a New Yorker versus Aniston's California lifestyle played a role in their breakup.

The couple looked so sweet in the photo posted on Theroux's Instagram.

During an interview with Refinery29, Aniston shared more private details about their relationship.

"He steals my shampoo, my hair paste ... Whatever product I put on my face, he just does the same for him," Aniston said. "You know, he likes to dabble. He kind of manscapes, which I actually enjoy. I enjoy a nicely manscaped partner."

In an interview on "The Ellen DeGeneres Show" shortly after, Theroux admitted that he does in fact borrow Aniston's products.

"I steal some of her products occasionally," he said. "I'm not shaving my legs or anything, but if she has a nice cream and she's washing herself with something that smells nice, I might borrow it."

In regards to manscaping, he said that he prefers being natural.

"I keep it pretty natural down there," Theroux said. "I think that's what we all do."

In an interview with Amy Sedaris for Harper's Bazaar, Aniston discussed her secret wedding.

Sedaris called the wedding "perfect" and noted that "everyone was dressed like a bunch of woodland creatures, and your [Aniston's] dress looked so beautiful and breezy."

"It's funny, I just gave Justin our edited video of the wedding for our anniversary, and it was fun to revisit it," Aniston said.

Aniston also shared details about her first thought when Theroux proposed.

"When Justin proposed, he put that freaking ring on my finger, and I was like, 'Holy crap, now I'm gonna have to get manicures," she said.

According to Us Weekly, it was an attempt to salvage what was left of their marriage.

"There was a time when I thought there was something romantic about picking up and trotting off somewhere different every three months," Aniston said during the interview. "Now I'm becoming more particular about the projects I take. I look around at my husband and my dogs and our home, and there's nowhere else I want to be."

In a photo shared by her manager, the actress was seen posing with "Friends" co-star Courteney Cox and a few other friends in Malibu.

In an official statement, Aniston and Theroux confirmed that they broke up.

"Normally we would do this privately, but given that the gossip industry cannot resist an opportunity to speculate and invent, we wanted to convey the truth directly," the statement read. "Whatever else is printed about us that is not directly from us, is someone else's fictional narrative. Above all, we are determined to maintain the deep respect and love that we have for one another."

After news of their confirmed breakup spread, many in the media weighed in on reasons that might have led to their separation.

"The good news is that was probably the most — I'm choosing my words really carefully — it was kind of the most gentle separation, in that there was no animosity," he told the New York Times. "In a weird way, just sort of navigating the inevitable perception of it is the exhausting part."

The actor added that there was no animosity between the exes.

"Again, neither one of us is dead, neither one of us is looking to throw hatchets at each other," he said. "It's more like, it's amicable. It's boring, but, you know, we respected each other enough that it was as painless as it could be."

Theroux also called the split "heartbreaking" because "the friendship would not be the same."

"But the friendship is shifting and changing, you know, so that part is something that we're both very proud of," he said.

"Happy Birthday to this fierce Woman. Fiercely loving. Fiercely kind. ....and fiercely funny. ❤️ you B," Theroux captioned a black-and-white photo of Aniston.

"She actually texted me. She said, 'You haven't followed me,' and I said, 'Of course I followed you!' and she's like, 'No you haven't!'" Theroux told Entertainment Tonight. "I realized I was one of the people caught in the glitch. So, I had followed, commented..."

Aniston broke Instagram when she joined in October 2019.

A representative for the app confirmed to CNET that there were some technical problems, which made some users unable to follow her at first, but that they were quickly resolved.

"Grabbing 2020 & another year just like...," Theroux captioned a funny and candid black-and-white photo of Aniston. "Happy Birthday B ❤️."

"Happy birthday @jenniferaniston," Theroux captioned a black-and-white photo of Aniston on a spiral staircase. "❤️you B!"

"That's a narrative that is not true, for the most part," Theroux said of the reports that Aniston wanted to live in LA while he wanted to say in NYC.

"Look, people create narratives that make themselves feel better or simplify things for them, " he continued, "That whole 'This person likes rock 'n' roll, that person likes jazz. Of course!' That's just not the case. It's an oversimplification."

Theroux also said that years after their breakup, he and the actress remain on friendly terms.

"We don't talk every day, but we call each other. We FaceTime. We text," he said.

When asked about how he navigates going from a romantic relationship to a platonic one, the "Maniac" star said: "Like it or not, we didn't have that dramatic split, and we love each other."

He continued: "I'm sincere when I say that I cherish our friendship. We can not be together and still bring each other joy and friendship. Also, she makes me laugh very, very hard. She's a hilarious person. It would be a loss if we weren't in contact, for me personally. And I'd like to think the same for her."
