Petra Kvitova, the top seed at the inaugural BNP Paribas Katowice Open, was welcomed by VIPs.
Kvitova, a big threat on clay and an even bigger threat indoors, was given a special welcome gift.
And then it was time for the official opening ceremony for the inaugural BNP Paribas Katowice Open.
The tournament spoke at the opening ceremony - can you guess the three players in the background?
The three players were the Top 3 seeds - Petra Kvitova, Roberta Vinci and Klara Zakopalova.
Poland's Marta Domachowska, a three-time WTA finalist, at her pre-tournament press conference.
Alizé Cornet, the No.5 seed at the BNP Paribas Katowice Open, at a Babolat autograph session.
Cornet, who has been ranked as high as No.11 in the world, signed autographs for her many fans.
Unfortunately Cornet wouldn't make it too far in the draw, falling first round to Anna Schmiedlova.
Kvitova made a special trip to the Upper Silesian Children's Health Center on Tuesday afternoon.
Kvitova met and passed gift bags around to some of the children who were staying at the hospital.
Kvitova also took some time out to spend some quality time with a few of the sick children.
Joining the World No.8 on the trip was Klaudia Jans-Ignacik, who is expecting her baby in July.
And the stars of the ATP World Tour have also been making appearances at the Polish WTA tournament.
Jerzy Janowicz and Lukasz Kubot held a press conference, signed autographs and held a kids clinic.
Jans-Ignacik also took part in the kids clinic - she is working at the tournament as an emcee.
Janowicz shot to fame last fall with a breakthrough run to the final of the Masters stop in Paris.
Kubot put himself on the map with a pair of second week runs at the Slams, one in 2010, one in 2011.
Another pair of Polish ATP World Tour stars are here - Mariusz Fyrstenberg and Marcin Matkowski.
