Justin Theroux: Jennifer Aniston's Boyfriend Has a Girlfriend!

Serial dater Jennifer Aniston has most recently been linked to her 'Wanderlust' co-star Justin Theroux. Numerous reports say the two have often been seen together looking quite affectionate towards each other, but it hasn't officially been confirmed that they're dating. According to Page Six, one person who's not jumping for joy over Jennifer's new love interest is Justin's girlfriend Heidi Bivens!

“Heidi and Justin have been together for 14 years. They met when she was 20 years old and he 24, and yes, she just moved out of their home last weekend. She has no comment.”

Ouch. So Jen isn't just a high-priced Hollywood whore, she's a home wrecker, too. I knew she had it in her. If there's a man in sight that Jen wants to sink her teeth into, she'll whip out the claws at any b!tch that stands in her way. Yeah, like Jen could be that evil... I wish!

Another source says the relationship was already over "between him and Heidi before he got close to Jen."

Well, damn. I was really hoping Jen was the dirty girl who would lie, cheat and steal for some peen, but if Heidi and Justin were already dunzo before she came into the picture, I guess she's not that bad after all.
