Not only does tennis superstar Serena Williams have a new baby -- now she has a new zip code too since the 23-time Grand Slam winner purchased a $6.7 million home in Beverly Hills. The newly constructed three-story home is a Spanish-style residence with five bedrooms and seven bathrooms. It sits on a quarter-acre lot in a gated community. Williams has put her Bel Air mansion on the market for just under $12 million.
