Jude Law and Sienna Miller are apparently rekindling their romance. According to London’s Daily Mail, the two went on holiday in Barbados with Law’s three children just in time to celebrate their birthdays together (Miller turns 28 Monday, while Law turns 37 Tuesday). The pair split four years ago after Law had an affair with his children's nanny, but they reconnected while starring in a play together in New York in October. According to an unnamed source close to Law, "Jude told his parents, children, and his ex-wife over Christmas that he wants to make a real go of it with Sienna. He really wants it to work this time around." Law had spent Christmas with Sadie Frost, the mother of his children, who reportedly became irate when Law told her she'd have to pay her own way if she wanted to join him and the kids on holiday in the Caribbean.
