Popular tennis star and part-time model Anna Kournikova is featured in K-Swiss’s new “Keep it pure” ad campaign.

Kournikova, who will be in Schenectady-Albany area when her St. Louis Aces visit the NY Buzz, will join Tommy Haas and Alona Bondarenko among the other tennis stars in the new campaign.

Kournikova made an appearance at the opening of the new K-Swiss store in Santa Monica where she spoke of her training regimen.

"I feel great when I sweat and get all the negative energy out," Kournikova told PEOPLE Magazine last Wednesday. "It's all about building muscle and feeling good about yourself," she says. "I do some cardio but very little, just to relieve the stress and sweat."

Please call 518-378-BUZZ regarding World Team Tennis ticket information for Anna Kournikova night on July 22 or for Serena Williams night on July 9.
