Prince William and Kate stress out while watching the Wimbledon final

LONDON -- The Duke and Duchess of Cambridge are just like the rest of us non-royals who were watching Sunday's men's Wimbledon final unfold between Novak Djokovic and Roger Federer. They were stressed.

Avid tennis fans and players, the Duke and Duchess of Cambridge -- can I just call them Kate and Wills like everyone else in Britain? -- were front and center in the Royal Box to take in the final. The pair appeared to be cheering a little louder whenever the five-set match swung Federer's way, and they even comforted him after the loss.

"I wasn't in a great state," Federer said, when asked if see the Duke and Duchess after the match. "I was unbelievably sad at that moment just when I left the court, so it was a difficult moment for I think the three of us. But they were very sweet to comfort me and wish me well, that they enjoyed the match and all these things. We met previously, so that helped I think. Clearly it makes me very happy to see them being supportive of my game and supportive of tennis."

The Duke and Duchess were also some of the first to congratulate Djokovic after his well-earned win.
