Serena Williams is a Bikini Babe

Tennis champ Serena Williams and former Destiny’s Child member Kelly Rowland hit Miami Beach together on Friday afternoon.

Serena, 27, has a book called “Queen of the Court” scheduled for release Christmas 2009.

Mike Jones, Simon & Schuster’s editorial director for non-fiction said of the book, “It’s a fantastic story about her background and how both her sister [Venus] and she were pushed into becoming winners by their father. She has huge appeal because of what she has achieved during her career. This book goes beyond tennis fans. She’s a top athlete with a really great personality and interesting story behind her.”
