NEW YORK, NY, USA - Serena Williams is only a few days away from starting her US Open title defense. So what does the World No.1 do to relax?

One of her favorite hobbies, karaoke. Williams sang Diamonds Are a Girl's Best Friend. She looked as comfortable on stage singing and dancing as she does blasting aces on the tennis court.
