Why tennis stud Andy Roddick shaved his head: “I must have been having a Britney Spears moment.”

Andy Roddick has always been a great wit and his sense of humor was again on display at a tournament in Atlanta this week when he explained his shaved head to the media: “The haircut was my idea. I must have been having a Britney Spears moment.”

The pop star, of course, famously shaved her head during a very public meltdown a few years ago.

Andy is recovering from an unexpected fourth-round loss at Wimbledon where he was trying to win the title for the first time after three runner-up finishes.

Andy is now turning his attention to next month’s US Open where he was champion back in 2003. He is playing in the Atlanta tournament to regain the terrific form he had earlier in the season when he amassed a 26-4 hardcourt record.

Atlanta is where Roddick won his very first career title. The year was 2001 and was the last time the tournament was played in that city before this year.

Joked Andy: “I guess that makes me the defending champion.”
