Redfoo has been making tennis headlines off the court. Now it's time to see what he can do with a racket.

Victoria Azarenka's beau -- real name Stefan Gordy -- has entered the 2013 U.S. Open National Playoffs. The playoff affords an opportunity for anybody 14 and over to earn a spot into the the U.S. Open through a series of sectional tournaments and playoffs that culminate in three championship events -- men's and women's singles and mixed doubles -- at the New Haven Open at Yale in August. Winners of the men's and singles playoffs earn a spot in the U.S. Open qualifying draw, while the mixed doubles winners get direct entry into the main draw.

What was said in Nadal-Federer handshake

Gordy has entered the event in both men's singles and mixed doubles, where he'll partner not with Azarenka but 17-year-old Ayaka Okuno. The musician actually coaches Okuno, No. 28 in the ITF Junior World Rankings.

“As a kid, it's always been a dream of mine to play professional tennis,” Redfoo said in a release. “Thanks to the U.S. Open National Playoffs for giving good players with a dream the chance to qualify for one of the biggest tournaments -- the U.S. Open. Every day I see my dream!”

Gordy, who played tennis as a junior, has been a fixture at tennis events since the U.S. Open last year, when he crashed Azarenka's post-match press conference. Since then he's been in Istanbul at the WTA Championships, the Australian Open and Indian Wells for the BNP Paribas Open. He also sponsored the Party Rock Open, a USTA Pro Circuit women's event last September.

Here's a preview of what to expect from Gordy on the court, as he picked up a racket to hit with Serena Williams during the BNP Paribas Showdown at Madison Square Garden earlier this month. He's really not bad.
