Tennis star Serena Williams reveals she used to have body issues

World number one tennis star Serena Williams has revealed that she used to have issues with her body when she was growing up.

The 32-year-old thought that she should have had a more athletic figure when she was younger, but has now learnt to "embrace" her curves.

"When I was young I thought I should be built more like an athlete, long and lean, not with a womanly figure," Williams told the May issue of Fitness magazine.

"But then people my age started coming up to me and saying, 'I love you because of the way you look.' That was really motivating.

"So I learned to be proud of my curves and embrace my large boobs. It's all about loving who you are and realising that you're beautiful."

Williams is the reigning French Open, US Open, WTA Tour Championships and Olympic champion.
