WorldTeamTennis.comEach year, Elton John and his friend, tennis legend Billie Jean King, host a charity tennis tourney called World Team Tennis Smash Hits.  This year's event takes place Tuesday night in Pittsburgh, Pennsylvania, and you can watch all the action live online.

The event begins at 7 p.m. EDT at EltonJohn.com or WTT's official site.  Joining Elton and Billie Jean this year are tennis greats like Andy Roddick, Andre Agassi and Steffi Graf.  The event opens with Elton participating in a celebrity doubles match, followed by another match that pits all-star teams against each other, one captained by Elton and one captained by Billie Jean.

This is the 20th annual Smash Hits tournament.  Over the years, it's raised over 10 million dollars for the Elton John AIDS Foundation and local AIDS charities.  This year's event benefits EJAF, and the Pittsburgh AIDS Task force.
