The world’s most famous royal bridesmaid is back at the world’s most famous grass tennis courts.

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.
