Author JK Rowling.

Author JK Rowling has defended tennis ace Serena Williams online.

Rowling jumped to the athlete’s defence on Twitter after the six-time Wimbledon champion was targeted by an internet troll over her physical appearance, reported Ace Showbiz .

“Ironic then that main reason for her success is that she is built like a man,” the hater wrote, to which Rowling quickly fired back, “Yeah, my husband looks just like this in a dress. You’re an idiot.”
