There was a lot going on in Paris even before the tournament began - including the draw ceremony.
Maria Sharapova joined fellow defending champ Rafael Nadal in the traditional draw ceremony Friday.
Four of the biggest names in the sport, including Sharapova, took part in a night of Nike tennis.
Nadal and Sharapova teamed up against Serena Williams and Roger Federer in a special doubles match.
Between them, the four players have 47 Grand Slams - but what's the breakdown of those 47 majors?
Federer has the most with 17, followed by Williams with 15, Nadal with 11 and Sharapova with four.
All four are among the favorites at the French, too - No.2 seed, No.3 seed, No.1 seed and No.2 seed.
Meanwhile, Ana Ivanovic and Jo-Wilfried Tsonga had an autograph session at the adidas store in Paris.
Ivanovic is a former World No.1, while Tsonga has been as high as No.5 on the ATP World Tour.
Victoria Azarenka at practice. This is the only major Azarenka hasn't been to the semifinals of.
Sharapova has fared much better here, completing her Career Grand Slam right here a year ago.
And Williams also has one title here, but four or more at all of the other Grand Slam tournaments.
Azarenka in press. The World No.3 is the last player to beat Williams, in the final of Doha.
Li Na won her first - and so far only - Grand Slam here in 2011, Asia's first Grand Slam champ.
And a feel good story - Heather Watson returns from a lengthy bout with illness at Roland Garros.
