Jennifer Aniston has been drinking to excess and obsessing over Angelina Jolie, claims a new report.

The actress and poster girl for lonely women needs to curb her unhealthy habits, according to Britain's Now magazine.

“Jen’s perspective is that it’s better to have two or three glasses of red wine than to take a sleeping pill to get to sleep,” says a source.

“The other day, she was tipsy and ranting at friends about Angelina Jolie, which they see as an unhealthy obsession of Jen’s.

“She’s still bitterly competitive with Angelina and it’s the subject that’ll come up time and time again after she’s had a few.”

The source adds: “The problem is that Jen’s so tiny, just a few glasses can really knock her out."

“Her drinking is certainly not excessive by British standards.”
