Sienna Miller has invested in a plush London bachelor girl pad to help her move on from her split with Jude Law. Law, 33, ended their turbulent relationship earlier this month (NOV06) because he reportedly couldn't keep up with the 24-year-old's party lifestyle. And the CASANOVA actress has snapped up a flat in London's St John's Wood for GBP1.2 million ($2.16 million) without a thought for Law and his three kids. A source tells British newspaper the Daily Mail, "It's very modern and trendy, but it's got no outside space at all and is not child friendly."
