Serena Williams has made fast friends with Kelly Rowland. Williams and Rowland were spotted vacationing at Miami Beach. Williams looked great rocking her white bikini. Rowland was content sunning just her shoulders. Williams issued a statement to announce her withdrawal from playing the Kremlin Cup in Moscow. Williams has a left ankle injury and she would like to rest and recover. This may mean Williams will not finish this season as the world’s Number One in women’s tennis ranking. Rowland has started recording her third full length album.
