The `Sherlock Holmes` actor and the 29-year-old beauty have split for a second time and although it was claimed the separation was a mutual decision it has been alleged the actress was responsible for the break-up. A source told the Daily Mail newspaper: "Clearly things aren`t particularly rosy in Jude`s personal life. "All I can say is that`s he`s gone through a rough time. These things are hard - it`s awful. The good thing is that he`s busy. He`ll keep on working. He`s shocked by this." While Jude has been spending time with ex-wife Sadie Frost - the mother of his three children, Rafferty, 14, Iris, 10 and Rudy, eight - in the wake of the split, Sienna has reportedly grown close to Joe Armstrong, her co-star in new West End play `Flare Path`. The pair have been enjoying each other`s company outside of rehearsals, but Sienna is not yet ready to date. A source said: "Sienna is still young and, in time, wants to get back out on the dating scene. "For now, she`s burying her head in work. Her colleagues have been brilliant. She gets on really well with Joe in particular and they`ve been hanging out a bit outside of the theatre."
