{blackbabes} JK Rowling smacks down Serena Williams Twitter troll

Serena Williams just won her sixth Wimbledon title, for which British superstar author JK Rowling took to Twitter to congratulate and commend the tennis superstar.

"#SerenaSlam! I love her. What an athlete, what a role model, what a woman," writes the "Harry Potter" author.

But of course, there's always someone out there who can't live by the adage "If you don't have something nice to say, don't say anything at all." One Twitter twit named Rob fires back at Rowling, "Ironic then that main reason for her success is that she is built like a man."

Rowling responded in the best way possible, posting a pic of Williams looking smokin' hot and writing, "'She is built like a man'. Yeah, my husband looks just like this in a dress. You're an idiot."
