Serena Williams inspired by Michelle Obama

Serena Williams has revealed that she was inspired by the watching Michelle Obama as she won her opening singles match of the Olympic Games.

The American brushed aside Serbian Jelena Jankovic 6-3 6-1 on Centre Court with the First Lady in the crowd.

"It was great seeing Michelle there," Williams told reporters. "It just made me want to play better and I felt even better.

"We're here for our country and to play well. I loved her dress, which is always nice. She is always looking good."

Williams, who won a fourth Wimbledon title at the All England Club last month, will now face Poland's Ursula Radwanska in the second round.
