Brad Pitt could learn a lot from James Rousseau.

The British model has somehow gotten Kate Bosworth to eat food - sadly, it seems as though Pitt may need to follow suit when it comes to his main squeeze.

Reports are spreading that Angelina Jolie has had such a difficult time since moving to New Orleans in January that she's simply stopped eating.

It all began when the actress lost her mother, Marcheline Bertrand, to cancer last month.

The 5-foot-8 star now weighs 109 pounds, says a source close to the couple. "She isn't eating."

She's also "very lonely and desperate to make new friends," the same source states.

It's too bad Anna Nicole Smith passed away. She was also looking for a pal.

The source adds:

"Brad has been worried about her day and night. She has been under so much stress, and Brad is trying to be understanding."

He's also trying to understand how a one-legged woman can ever win Dancing with the Stars.
