Stars have been holding court at Wimbledon since the annual tournament kicked off earlier this week, and on Thursday, Pippa Middleton popped up at the games in London with her hot, younger brother James [1], 31. The 34-year-old expectant mom [2] made a stylish arrival in a white dress and espadrille wedges [3], while James looked dapper in a navy blazer complete with a matching tie. The only thing that would have made this outing even better was if Kate had joined them, but she's currently enjoying the rest of her maternity leave [4]. Oh well, at least we still get to swoon over James. See more of Pippa and James's sibling outing ahead!
