Sienna Miller got a head start on her holiday vacation in Barbados last week when she hit the beach in her bikini alongside her mother Jo. As expected, she and her mom got a little more company over the weekend in the form of her apparently on-again boyfriend Jude Law and his three oldest kids, Rafferty, Iris, and Rudy. Sienna was in a gingham Agent Provocateur suit Kate Moss also owns to spend yesterday playing in the water with Jude's kids. Jude's ex, Sadie Frost, is said to be unhappy Jude didn't buy her a ticket to join them all, but he didn't seem to be letting any stress ruin his fun family times. He's got lots more to celebrate at the moment anyway, including Sherlock Holmes being second place at the weekend box office, Sienna's 28th birthday today, and his own big day tomorrow.
Lots more photos from their vacation so just
