Forget the same zip code! Priestley and Pitt lived in the same apartment in 1987 when both were aspiring actors in L.A. "Just for fun, we used to have competitions over who could go the longest without showering and shaving," the Beverly Hills 90210 star revealed in his memoir Jason Priestley: A Memoir. "Brad always won. Having to go on an audition meant cleaning up, which is what usually put an end to the streak."

The former child stars moved in together after meeting at a Vanity Fair photo shoot. And "move in" is about all Lilo did. "She paid rent, and she was there probably three times," Raven-Symone said. "She had her clothes in the apartment we were supposed to live in together." No word if she ever unpacked them.

The late-night host and Goldbergs star roomed together in Chicago when they were both kicking off their comedy careers in the '80s. Their apartment was in a prime spot — across from Wrigley Field — but didn't come with many amenities. "There was no air conditioning in the apartment," O'Brien said. "Jeff Garlin had air conditioning in his room. But my room had no window."

These two might seem like an unlikely duo, but they were college roommates at Harvard in the '60s and promptly became BFFs. (They even joined a country band to woo the ladies.) Their friendship still endures: The Oscar winner spoke at the 2000 Democratic National Convention, where he revealed that they once celebrated Thanksgiving by wrapping a turkey in tin foil and roasting it in their dorm.

Yes, y'all. Mrs. Coach and Lorelai Gilmore once lived in an empty house back in the day. "We had no furniture and all we ate were Rice Krispies Treats," Graham revealed on Watch What Happens Live.

When Badgley was 18, he lived with the Heroes star, who's almost a decade older — and reaped the benefits. "I used to borrow his ID to get into bars," he told Bullet magazine. "I've still got it somewhere."

Before they were Oscar winners, Hunter and McDormand were randomly placed roommates at the Yale School of Drama and they continued living together after graduation in New York City. They later roomed in L.A. with Joel and Ethan Coen (McDormand married Joel in 1984), and co-starred in the directing duo's Blood Simple and Raising Arizona.

Sounds like these two are better off as pals than roommates. The Accepted co-stars "fought like a married couple" when they lived together in L.A. "Jonah would recycle everything," Long said. "We started getting in little fights — he left the bathroom door open, didn't clean up after himself. Little things like that."

The actors were paired as roommates at Julliard in the '70s and became lifelong friends. In his memoir Still Me, Reeve recounted how Williams surprised him in his hospital room as a proctologist while he was awaiting spinal surgery. "For the first time since the accident, I laughed" Reeve wrote. "My old friend had helped me know that somehow I was going to be okay."

The former American Idol judges bunked together for a year, and Abdul dubbed the songwriter the "best roommate." Except for the sleepwalking. "She walks in her sleep!" she said. "I'd wake up in the morning and I thought, 'Did my dog do this?' There was food on the ground... but she would have no recollection that she did it."

Oh, what we would give to have been a fly on the wall in this bachelor pad. The erstwhile Jack Bauer moved in with RDJ when he first landed in Hollywood and they lived together for three years. Just imagine the parties.

The actor and director were roommates at the University of Texas at Austin, where they made their first collaboration, Anderson's directorial debut Bottle Rocket. Anderson scored the bigger bedroom in their condo by writing a paper for Wilson about Edgar Allan Poe, which earned Wilson an A and was dubbed "magnificent and droll" by his professor.

The actors grew up in the same town and lived together in the Windy City while studying acting. The former pals had a falling out in 2007 when Cuscak quipped to Best Life magazine of how the Entourage star was handling success: "No comment. I mean, you could fill in the blank, I bet."

Hey, girl. Did you know that these two hunks lived together when they were on The New Mickey Mouse Club? Timberlake's mom was Gosling's guardian for six months because the actor's mother had to remain in Canada. "We used to do terrible things,' Timberlake said on The Ellen DeGeneres Show. "We stole a golf cart. We were like 'Yeah, man, we stole a golf cart. You know what it's like on a back lot — there are golf carts everywhere. We drove into MGM studios, which is totally illegal, by the way."

If you thought Williams and Gosling gave lived-in performances in Blue Valentine, there's a reason: They lived together! Director Derek Cianfrance asked the actors to shack up for a week, but they ended up living together for a month with their on-screen daughter. "He's so hard to hate," Williams joked. "It's hard. He does the dishes and he takes care of the kids!"

The Oscar winners first met in 1957 at the Pasadena Playhouse. After moving to New York the following year, Hoffman crashed on the floor of Hackman's tiny one-bedroom apartment that he shared with his wife. "I slept on his floor because he had this small bedroom and then, he had this little teeny bit larger room where there was the stove with a board over it," Hoffman said. "Next to the stove was a tub, which was also the sink, and it had a board over it. I would have to take a bath while they were making breakfast. There was also a toilet next to the bath, and all he's thinking about is that when I had to have my morning bathroom, I didn't care whether they were making eggs or not. He's held that against me for 40 years."

The Gossip Girl stars lived together for two years after the show started in 2007. "Ed and I became roommates here in New York because we didn’t know if the show was going to last or not," Crawford told Interview. "Ed had never lived away from home, let alone in a different country. We got along and figured it would be a smart move financially. And really, it was also just kind of out of laziness."

The lifelong friends bunked together while they were writing their Oscar-winning breakout Good Will Hunting. "We rented this house on the beach in Venice and 800 people came and stayed with us and got drunk," Affleck said. "Then we ran out of money and had to get an apartment."

The Glee stars lived together until Agron had to move out because she was allergic to Michele's cats. But the actresses left their catfights at work. "We have these smackdowns at work and come home and are like, 'Wasn't it so funny when we were fighting today? Let's make cookies!" Michele joked to New York Magazine. "It works out. We're both vegans. Well, I was. I slowly dipped back into cheese."

The studs lived together in London in the early '90s while they were struggling actors after being introduced by a director. The two later started their own production company called Natural Nylon.

The Romancing the Stone co-stars lived together in New York in the '60s, but DeVito was already thinking about living with someone else: future wife Rhea Perlman. "He was neat. That’s not very good for his image! But he was neat, and he was in love with Rhea," Douglas said. "So actually, he was a great roommate because I didn't see him a whole lot — because he was with Rhea the whole time. He was so neat."

Hayek took in Cruz when the Spanish actress first arrived in Hollywood. "We slept in the same bed so many times and it was like she was always trying to wake me up and call me huevos," Cruz told Allure.

Long before (the excruciatingly long) Funny People, Apatow and Sandler lived together in a $900 per month apartment in the Valley. Sandler slept on a mattress with no sheets and took umbrage when the director used his bathroom. "Back then, life was just doing stand-up or writing jokes. You would sleep until noon every day and kind of stumble out," Apatow told 60 Minutes. "You would have to be at work at 8:30 at night. Work was sometimes 15 minutes."
