Sienna Miller Is Running On Empty

Sienna Miller breaks down and almost starts to cry when the paparazzi question her in Malibu, Calif., on Monday.

The 26-year-old actress was trying to fill up her Lexus at a Malibu gas station, when one of the paparazzo questioned Sienna about her alleged homewrecking.

“Can you leave me alone, I’m trying to get gas and this is really harassment. Please leave me alone,” Sienna said. “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***** fill up my car.”

After she left the gas station Sienna pulled into the Police Department’s Emergency Safety Zone to ask for an escort home.
