The doubles tandem of Lucie Safarova and Bethanie Mattek-Sands are no strangers to winning, and lately, dancing. On Wednesday, "Team Bucie" reached the Indian Wells semifinals with a win over Svetlana Kuznetsova and Kristina Mladenovic, and celebrated with a post-match dance.

The Tennis Channel's Sloane Stephens sat down with the world No. 1-ranked Mattek-Sands to talk about swag, Safarova and their famous Australian Open victory dance.

It's no secret that Safarova and Mattek-Sands have chemistry. They have won nine titles together including four majors. But they also clearly know how to have a good time, let loose, and share a laugh or two (as they did when they got interviewed by a room full of second graders).

Mattek-Sands and Safaraova will face Martina Hingis and Yung-Jan Chan for a spot in the final.
