Jennifer Aniston snuck out of the Sunset Tower Hotel in LA last night with a smile on her face but no John Mayer. In fact, we haven't seen her with her supposedly on-again man since last week, which has some worrying that they're over already before they even really began. While most of you would be relieved to see them apart, I still hope they work out. An Australian magazine is even claiming that the reunion happened because Jennifer is pregnant, but seeing how recently we saw her perfect bikini body, I have trouble believing that one. Either way, she's got loads of friends by her side and an adorable movie coming out — you must check out the Marley & Me trailer — to keep busy if things don't work out again with John.
