Harry Potter author JK Rowling has blasted a Twitter user who claimed 2015 Wimbledon tennis champ Serena Williams is "built like a man".
Rowling shared a photo of herself posing with the sportswoman after Saturday's big win.
Twitter user Rob @danielstorey85 responded by saying: "nowhere near when Graf and Navratilovaplayed all women were on a similar level not muscle bound exceptions like now. Ironic then that main reason for her success is that she is built like a man."
Rowling responded with a photo of curvy Serena in a red dress waving to fans with the caption: "She is built like a man". Yeah, my husband looks just like this in a dress. You're an idiot.
