On October 12, 2008, Anna Kournikova played one exhibition match for the annual charity event, hosted by Billie Jean King and Elton John, and raised more than $400,000 for the Elton John AIDS Foundation and Atlanta AIDS Partnership Fund. She played doubles with Andy Roddick (they were coached by Elton John) versus Martina Navratilova and Jesse Levine (coached by Billie Jean King); Kournikova and Roddick won.
Kournikova competed alongside John McEnroe, Tracy Austin and Jim Courier at the Legendary Night, which was held on May 2, 2009, at the Turning Stone Event Center, Verona, New York. The legendary night of tennis consisted of a grudge match between McEnroe and Courier in singles followed by a mixed doubles match of McEnroe and Austin against Courier and Kournikova.
She is the current K-Swiss spokesperson. In a feature for Elle magazine's July 2005 issue, Kournikova stated that if she were 100% fit, she would like to come back and compete again.
In June 2010 Kournikova reunited with her doubles partner Martina Hingis to participate in competitive tennis for the first time in seven years in the Invitational Ladies Doubles event at Wimbledon. On 29 June 2010 they defeated the British pair Samantha Smith and Anne Hobbs.
