Sienna Miller busted up Balthazar Getty’s marriage and now Karma has come back to bite her in the ass. Sienna has fled the States after major fights about her party-girl lifestyle and his wife and kids. Former addict Balthy prefers a quiet lifestyle and he can’t seem to committ to her over his wife.

Friends say the 26-year-old actress fears the relationship is ‘as good as over’ because the father of four has refused to file for divorce from his wife of eight years, LA-based clothes designer Rosetta Millington.

Oh well, Sienna. That’s what you get when you go diggin’ in another woman’s garden.
