Photos of Jennifer Aniston in LA Amid Rumors of Another Breakup With John Mayer and Possible Pregnancy

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.
