Looks like Kate Bosworth had a relaxing birthday, celebrating the big 25 today with her friends in Sydney. Spending some time in the Australian Summer seems like a pretty sweet deal, and we bet she follows it up with some partying tonight. Her cute boyfriend James was right there with her on the beach, and we know how much this couple loves a warm weather vacation. We can't help but wonder if he had any romantic surprises up his sleeve to help make her birthday even more special.
