Victoria Azarenka's distinctive grunts made into music Redfoo has been seen cheering from Azarenka's players' box and signing autographs during most of her matches at the Australian Open. Azarenka told the Australian media that Redfoo, the LMFAO frontman whose real name is Stefan Kendal Gordy, had to fly to a concert in Malaysia but planned to come back later in the week. Redfoo is also the son of Motown Records founder Berry Gordy. Azarenka told a post-match news conference that music is a "very important" part of her pre-match preparation. It helps "focus, pump you up, get your feet a little bit moving, kind of get excited," she said. I kind of get in the zone. It just makes me feel good inside. When I feel good inside, I love to go out there and do the best job as I can. Azarenka has dropped only one set as she goes into the quarter-finals of the tournament. She now faces Russian Svetlana Kuznetsova. Kuznetsova advanced after a 6-2, 2-6, 7-5 win over Caroline Wozniacki, a former No. 1-player who will now slip out of the top 10. Kuznetsova said she noticed a difference in the temperament of Azarenka, who was prone in the past to hot-headed outbursts on court. "She's changed and just become so stable," said Kuznetsova. I think she just got calmer. She's consistent. Azarenka smiled when told her opponent had complimented her composure. "I'm always going to be an emotional player," she said, adding that now she's learning how to pick the right reaction for each point. "Sometimes you need to be more aggressive ... to pump yourself up," Azarenka said. Sometimes you just need to relax and breathe.
