Shock, horror, I’m hearing that Sienna Miller has called time on her relationship with Balthazar Getty after just under a year.

The pair’s off/on relationship apparently came with too much baggage for commitmentphobe Sienna, who is famous for getting bored of her beaus after a few months. Getty, who has four kids with his wife Rosetta, only officially split with her after he was seen frolicking with a topless Miller on a boat last year…

Poor old Sienna Miller, not only does half of Tinseltown hate her since nicking Balthazar Getty from his wife (naughty!), but now her film career is taking a bit of a beating too.

Her latest movie, The Mysteries of Pittsburgh, is getting a right ol’ panning from the critics, not to mention the American public. (Word of advice love, calling Pittsburgh “Shitsburgh” during an interview is not going to endear you to the locals.)
