Sienna Miller 'breaks down in tears'

Sienna Miller allegedly broke down in tears after being confronted by paparazzi.

According to the Daily Mail, the actress wept when photographers questioned her about her relationship with Balthazar Getty at a Los Angeles petrol station.

When asked about Getty's wife Rosetta, Miller responded: "Can you leave me alone? I'm trying to get gas and this is really harassment. Please leave me alone.

"Please, I'm asking you. I can't live like this, please give me a little bit of respect. I'm just trying to f***ing fill up my car."

Miller is reportedly upset with tabloid reports dubbing her a "homewrecker" and is urging Getty to clarify his marital status.

"Sienna is being portrayed as a femme fatale and fears for her career because Hollywood hates a homewrecker," a source told the News Of The World.

"She hopes Balthazar can get Rosetta to put out a statement saying their marriage was already over."
