Roger Federer is back at Wimbledon. The eight-time champion at the All England Club was sitting in the Royal Box to watch Monday’s fourth-round matches on Centre Court, starting with his former rival Novak Djokovic playing Alex de Minaur.

Today, Federer and his wife, Mirka, returned to Wimbledon, again in the Royal Box—but this time, they were seated next to Birgitte, Duchess of Gloucester. (The Federers were also two rows in front of Kate’s parents, Carole and Michael Middleton .)
