Serena Williams got served today, but not on the tennis court. Maria Sharapova responded to the French Open winner's recent catty comments about an unnamed tennis player (widely thought to be Sharapova) and her "black hearted" boyfriend published in Roling Stone. So Sharapova was all, "If she wants to talk about something personal, maybe she should talk about her relationship and her boyfriend that was married and is getting a divorce and has kids." Buuuurn. Williams is a favorite to win Wimbledon, which starts Monday. So maybe she should focus on that. Her mouth has gotten her into enough trouble this week.
