Wuh woh. Sources are saying that Jennifer Aniston and Justin Theroux have moved in together. "They decided to rent a house while they keep searching for the perfect [one] to buy," a friend squeals. "Jen and Justin are very excited about living together in their new home." This information seems fairly reliable, as it comes after Jennifer sold her Beverly Hills home in July for a cool $38 million and after months of whispers that the two were house-hunting together. [People] And I'm a little concerned. These two are in a new relationship, and living together is tough. Not to mention that Justin broke up with his girlfriend of 14 years to get with Jennifer, which doesn't make him the strongest prospect for the future. It feels like he's after something here. Even Patti Stanger thinks so. I hope it all works out, but I'm just not sure. Take it a little slower, Jen! After the jump, other celebrities raised eyebrows when they decided to shack up.
