sienna millerSienna Miller’s step-mum Kelly Hoppen has confirmed that the actress is set to leave Britain after the reaction to her relationship with Balthazar Getty.

Sienna and Balthazar are said to have started dating at the start of June and after going public at the end of June, Balthazar confirmed his separation from his wife Rosetta - although sources differ on whether the couple actually split before or after he began his fling with Sienna. One graffiti artist has an opinion though: spray-painting the word ’slut’ onto the side of Sienna’s London home.

Kelly is quoted as saying: “It’s disgusting that she can not live in her own country. Now she’s going to have to leave the country to get on with life. She can’t live here now.

“Why is it that if a man leaves his wife the new woman gets all the s**t? That doesn’t happen the other way round.”

Last month, Sienna and Balthazar were rumoured to be looking at luxury homes together in a private area west of Malibu. Sienna’s dad Edward Miller was married to interior designer Kelly - who designed the Beckhams home in Los Angeles last year - for 15 years while Sienna was growing up.
