Sienna Miller has been spotted "snuggling up" to a folk musician. The "Factory Girl" star has sparked rumors she is dating upcoming star Marcus Foster after she watched him perform at a charity show in East London.

A source said: "Sienna was in really high spirits. She had quite a lot to drink and was laughing and joking with pals as she cheered on Marcus during his set."

Sienna Miller is "at war" with women.

The 27-year-old actress - who faced a backlash from her female fans after she began dating married actor Balthazar Getty - says other girls make her life tough.

She said: "I've been at war, without a doubt. I have really experienced the judgment of women in the past year. It's women who are holding us back. It's women who are judging. I find it sad. We say we want to be on an equal path, but men don't sit around bitching at each other. It's very competitive. There's no sisterhood."

Balthazar Getty will reportedly exit 'Brothers and Sisters' in an explosive storyline.

Studio sources have revealed episode 19 of series three will be the actor's last after he was written out of the hit US TV show.

Sienna Miller and Balthazar Getty want to star in a film together. The "Factory Girl" star - who was recently reunited with the married "Brothers and Sisters" actor following a brief split - hopes working together will win over critics of their romance.

A source told Britain's The Sun newspaper: "Her advisers are warning how unpopular that would be."

Sienna Miller and Balthazar Getty are back together.

'The Edge of Love' actress - who said at an event earlier this month she was "single at the moment" - was spotted walking her dogs and laughing with the 'Brothers and Sisters' star in London's Maida Vale district yesterday (11/27/08).
