Anna Wintour Cheers On Serena Williams At U.S. Open Women's Final As She Takes A Break From Fashion Week

Vogue magazine editor Anna Wintour took a break from sitting in the front row at New York Fashion Week to watch Serena Williams beat Victoria Azarenka for her fourth U.S. Open tennis title.

Wintour has attended the collection shows of designers such as Altuzarra , Victoria Beckham, and Marc Jacobs while in the big apple.

Earlier this year, Wintour was named one of the Most Powerful Women in the world by Forbes magazine due to her wealth, impact, and media presence.

Though Wintour has a reputation for being cold intimidating, she told Forbes, "I don't think of myself as intimidating. And I assure you that all the people who work for me on a day-to-day basis don't think that either."

Wintour has become a staple at recent tennis matches, as she also attended the U.S. Open last year to watch Roger Federer and Santiago Giraldo, and earlier this year, sat in the Royal Box with Kate Middleton and Prince William to watch Federer play in Wimbledon. Wintour is a huge fan of Federer's, as she featured him in Vogue Magazine back in 2009.

On Sunday, she sat in the family box with Serena Williams mother and coach, Oracene Price, and watched as Williams, 30, beat the No. 1 ranked player in the world, Azarenka, 23.

"I honestly can't believe I won. I was really prepared for my runner-up speech, because she was playing so great. I'm really shocked right now," Williams said after the match.
