Kate Middleton Making a Racket While Pregnant

Kate Middleton channeled her inner Serena Williams to grab a tennis racket and hit the court while carrying a child.

The pregnant Duchess of Cambridge was at the Lawn Tennis Association Tuesday in London to host the Tennis For Kids event, which inspires young children to hit the court.

You may remember, earlier this year Serena Williams revealed she was pregnant when she won the Australian Open.

Middleton was extremely graceful while running drills with the kids … and even got in a pretty good workout!
