The 25-year-old tennis superstar was born in Russia but moved to the US at the age of 7.

She has ranked No. 1 in the world on five separate occasions and has won 27 WTA singles titles, including four Grand Slam singles titles (out of seven finals appearances).

Maria first turned pro in April of 2001 at the age of 14 and stepped into the spotlight in 2004 at age 17, when she defeated two-time defending champion and top seed Serena Williams in the 2004 Wimbledon final for her first Grand Slam singles title.

After winning this year's French Open by defeating Sara Errani 6–3, 6–2, she became the 6th woman in the Open Era to complete the career grand slam.

In June 2011, she was named one of the "30 Legends of Women's Tennis: Past, Present and Future" by Time. In March 2012, the Tennis Channel named her one of the "100 Greatest of All Time."

She'll be the flag bearer for Russia at the Summer Olympics. We're hoping "flag" is code for "naked body."
