Roger Federer is "definitely done" playing professional tennis.

The 20-time Grand Slam title winner, 41, tells TODAY's Savannah Guthrie in an exclusive interview airing on Wednesday that he is firm on his decision to end his playing days.

"You know un-retiring is a thing now," Guthrie says in a clip of the interview. "Tom Brady, now Serena seems to be wavering a little. You're done?"

But Federer replies quickly: "No, no. I am definitely done, I know that, yeah."

Guthrie's sit-down with the tennis icon — and her widely discussed celebrity crush — happened in London, where the anchor was already located for the network's ongoing coverage of Queen Elizabeth's death.
