Jennifer Aniston's a 'Baster' bitch

Reports from the set of The Baster in New York suggest that Jennifer Aniston is being a bit of a bitch to castmates and crew since her relationship with songwriter John Mayer finished.

A source says: "She’s professional and gets through her scenes admirably but off set she’s clearly not happy. She’s been snapping at her co-stars and crew and keeping herself to herself quite a lot. Right now she’s on the warpath because she’s heard John has written a song about her. She’s so furious it’s a wonder she can even act happy."

Oh, could that be this song by any chance??? Heartbreak Warfare indeed! It's just a shame for the people working on this film that they're also casualties of Jen and John's bitter battle.
