Sienna Miller, 32, & Poppy Delevingne, 27. It appeared to be a case of single white female for fashion wannabe Sienna Miller when she roomed with model Poppy Delevingne in New York during the mid-Noughties. Speaking about Miller to Vogue UK, newlywed Delevingne joked: “She was like my heroine at the time. I just wanted to emulate her, and now of course we’re friends and I’m always telling her how I wanted to be just like her – she probably finds it quite scary.”

Brad Pitt, 50, & Jason Priestley, 44. In Jason Priestley’s autobiography Jason Priestley: A Memoir, the former Beverly Hills 90210 star revealed that he and the most handsome man in movies, Brad Pitt, actually roomed together in 1987, while trying to make it in Hollywood. “Just for fun, we used to have competitions over who could go the longest without showering and shaving,” writes Priestley. Apparently, though, “Brad always won”. Super gross!

Ed Westwick, 27, & Chase Crawford, 29. Brit-born actor Ed Westwick shared a New York apartment with his Gossip Girl co-star while filming the first two seasons of the hit TV show. Crawford allegedly moved out of their bachelor pad to a new apartment because Westwick was a total slob to live with! Sorry, Chase, but we’d never leave Ed, even if he didn’t do his share of the washing up

Ewan McGregor, 43 & Jude Law, 41. These two hotties didn’t just share a house together, they were allegedly so poor they had to sleep in the same room. The Hollywood hunks roomed together back in the early Nineties after being introduced by a director at the beginning of their acting careers in LA (We’d love to have been a fly on the wall). After a string of movie blockbusters the pair even founded a production company together called Natural Nylon.

Justin Timberlake, 33, & Ryan Gosling, 33. Ahlan!’s fave T’town hunk Ryan Gosling and pop sensation Justin Timberlake once lived together at Timberlake’s Memphis, Tennessee home. When the pair appeared as Mouseketeers on The Mickey Mouse Club a young Gosling’s mum had to keep her job in Canada so the youngster sought refuge with the Timberlake family. Justin famously said: “We were closer than the rest of the kids on the show just because we had to share a bathroom.”

Lindsay Lohan, 28, & Raven-Symoné, 29. It takes one brave girl to room with bad girl Lindsay Lohan, but American actress Raven-Symoné actually enjoyed the experience. The former child stars decided they wanted to experience the college lifestyle without actually having to study. The pair lived under the same roof for a while in 2005 while working in Hollywood. “She was really cool, actually, but became really busy with work, so we hardly saw each other,” said Raven.

Matt Damon, 43, & Ben Affleck, 41. These talented rascals became life-long mates after living together in the early Nineties. It was this flat share that changed their lives forever, propelling them to the Hollywood A-list. It was here that they started penning the script of Good Will Hunting, a film that won them an Oscar for Best Writing and Screenplay Written Directly for the Screen. They’re not only co-writers, co-stars and flatmates – they also happen to be tenth cousins!

Harry Styles, 20, & Louis Tomlinson, 22. At the beginning of 1D mania, these two heartthrobs rented a swanky Dhs18 million bachelor pad in Princess Park Manor, an exclusive apartment complex in London, which features tennis courts, swimming pool and a gym! Ooh, get them! Other celeb tenants living in the gated apartments included the McFly boys, The Wanted and girl group The Saturdays. Sounds like party central to us!
