Pippa Middleton Watches Serena Williams at Wimbledon

Pippa Middleton was spotted at Wimbledon Thursday watching the second-round action from inside the royal box at Centre Court in London.
Middleton – in a white, button-up sweater – likely stole some attention away from the women's singles match between four-time Wimbledon champion Serena Williams and Hungary's Melinda Czink.
Serena served a whopping 10 aces Thursday leading to a 6-1, 6-4 victory.
Kate's sister, 28, attended another match there with Alex Loudon one year ago Friday.
This time, the royal sister-in-law to Prince William was with her brother, James Middleton.
