Caroline Garcia, Agnieszka Radwanska and Andrea Petkovic hit the red carpet for some photos…

…along with Ana Ivanovic, Angelique Kerber, Kristyna Pliskova…

…Simona Halep, Kristina Mladenovic, Lucie Safarova, and more.

Defending champion Angelique Kerber joined tennis legends Michael Chang and Michael Stich and professional racing driver Mark Webber for a doubles duel.

Afterwards, the players of the Porsche Tennis Grand Prix – including Agnieszka Radwanska – were introduced to the spectators.

Simona Halep walked on with a bouquet of flowers…

… while Carina Witthoeft had a bit of a challenge getting her walk-on mascot to come along with her.

Kerber – Germany’s No.1 and Stuttgart’s No.2 seed – answered some questions for the crowd.

All of the players – along with their young mascots – were presented to the Stuttgart audience.

Ana Ivanovic is looking to do one better than her runner-up spot here in 2014…

… while No.5 seed Petra Kvitova is looking to put two second-round Stuttgart exits behind her.
