Casanova premiere, Jude and Sienna's hotel reunion

Jude Law and Sienna Miller reportedly locked themselves in a hotel room for 48 hours to try to rekindle their romance. The on/off couple allegedly booked into the swanky Shutters Hotel in Los Angeles to try to patch up their relationship, which has been on the rocks since Law admitted cheating with his children's nanny earlier this year. A source is quoted in Britain's The Sun newspaper as saying: "They've barely come out of their room. "They've told staff they want to be left alone." Last week it was claimed Jude angered the blonde actress by planning a holiday with his ex-wife Sadie Frost. The love cheat was said to be organising a safari holiday in Kenya with his ex and their three children, Rafferty, Iris and Rudy. However, Sienna is said to be furious because she knows the break will boost rumours that Jude could be getting back together with Sadie. A source revealed to Britain's Daily Star newspaper: "Sienna was livid when she found out. She was begging him not to go, telling him he is going backwards by becoming close to Sadie again." Sadie has already fuelled speculation she is getting close to Jude again, saying they have a great relationship. She told an Italian magazine: "My relationship with Jude is the first priority for me. I'm spending all my time with Jude - I can't do anything else." [TeenToday]
