Victoria Azarenka is finding major success in the US Open 2013, and the support from her boyfriend Redfoo could be helping her stay on her A game.

Stefan "Redfoo" Gordy, 38, son of music legend Berry Gordy, hasn't been in the stands to cheer on his Belarusian girlfriend, his music has been holding her to him and reminding her of his presence.

She told Hollywood Take in a recent interview that she listens to music that the Australia's "The X-Factor" judge made for her as she works out before matches at the U.S. Open.

"There's a lot of remixes that Redfoo does for me actually. So there's not really names of the songs," she said. "He did the remix to Beastie Boys, which is incredible. I listen to Rihanna ... you know, some other mixes. Those two are my favorites."

Redfoo has also been thinking of Azarenka while they are away from each other.

"I'm just really focused on being, like, the best cheerleader I can be," he told the New York Observer in a recent interview. "Do I get nervous? No way, man. I'm just constantly thinking about what does she need to do to win and what can I do?"

He also dished on how they met. Tennis Channel CEO Ken Solomon introduced them.

"She said, 'Hey, why don't you come to my press conference?' And I went to that. It's on YouTube. You can see it. It was crazy, it was fun, and we just became friends. We were friends for a long time and then, err, she seduced me!"

Redfoo even used Azarenka's on-court grunting into his single, "Heart of a Champion."

"I was making some stuff, I needed some new sounds, and I had an idea to put her grunt in there. Her grunt is actually perfectly in the key of F," he said.

According to HollywoodTake.com, Azarenka has been dating the former LMFAO frontman since last September.

But the website speculated that the two could be struggling in their relationship because he broke down in tears on "Australia's X Factor" while listening to a song called "Don't Let Me Go."

"I'm going through something right now in a relationship. And those lyrics made me cry. I wish I could show this to her now," Redfoo told the teenage contestant.
