Steffi Graf in zebra stripes

Tennis star Stefanie Graf wears a zebra-striped gown at the 14th Annual Grand Slam For Children benefit concert at The Wynn Resort Hotel Casino. This was in Las Vegas, Nevada on September 26, 2009. The event was a benefit for the Foundation For Education created by Graf's husband, Andre Agassi. Steffi Graf was born in 1969, so she turned 40 the year this photo was taken.
