Looks like Serena Williams has been getting a lot of rest since she withdrew from the U.S. Open to give herself time to recover from surgery to repair cuts on her right foot.

Or has the No.1-ranked tennis pro gone under the knife?

As our friends over at PopEater report, a stunning Williams attended the Hamptons Magazine cover party on Wednesday night in a leopard print dress. The tennis star's fresh-faced new look ignited a flurry of speculation over whether she'd undergone a cosmetic procedure or was just the recipient of a good makeover.

PEOPLE reported, "Williams was reportedly hurt by a broken glass at a restaurant while she was in Munich – shortly after winning her fourth Wimbledon singles title – last month and had surgery on July 15. "

Plastic surgery speculation aside, Williams is no stranger to the world of fashion. "When I get injured it's devastating because I know I won't be able to wear heels. I'm practically in tears," she told SoBeFit magazine earlier this month.
