Roger Federer on BFF Anna Wintour: "I Had No Idea Who She Was When I Met Her"

Roger Federer and Anna Wintour's unlikely friendship has been well-documented, but when The Hollywood Reporter caught up with the tennis great March 7 -- at a Moet & Chandon event at the Four Seasons to toast the brand ambassador's 1,000th career victory -- he was asked what people would be surprised to know about their relationship. "I had no idea who she was when I met her," said Federer, 33. "I was introduced to her, the editor of Vogue, and I said, 'OK. Fine. Now what?' "
The answer is that the two have became close friends, offered Federer: "She's very nice and gives us good advice," he says of him and wife Mirka, 36. Though he didn't say if it is of the sartorial variety, it could be about kids: Wintour has two offspring, while Federer and wife are parents of two sets of twins.
