Sienna Miller parties too hard, say friends

The Mirror is reporting that Sienna Miller is close to burning out by combining her busy career with an equally busy social life.

Sienna flitted from party to party during Oscar week and her behaviour worried her friends.

“She’s partying hard, some of us would say too hard,” a friend has revealed. “We sat her down and told her she needed to count to 10 and cool it.

“There was a scene with Sean Penn in the [Chateau Marmont] bar where she was being a little too familiar and we knew it was time to have a word.”

“Hollywood is a lot more po-faced about people having a good time than you imagine. It is an industry town and the industry is movies.”

“Sienna was having a good time, but it wasn’t the kind of behaviour the moguls like.”

A source from the set of Sienna’s latest film Factory Girl about 1960s party girl Edie Sedgwick has suggested that playing Edie might not have helped her current attitude.

“Sienna was totally absorbed by the part and it was hard for her to get out of character.”

“She seemed to become Edie - the resemblance between them was uncanny. It got to a point where it was hard to tell where Edie ended and Sienna began. But considering how Edie ended up, it’s not necessarily a good thing.”
