In the latest promotional video for On, Zendaya and Roger Federer engage in a fierce game of air tennis, which is precisely what it sounds like in a normal match without the ball. The video opens with the two running into each other at the On store, exchanging aggressive glances about Zendaya’s role as tennis star Tashi Duncan in Challengers.

Zendaya and Federer are closely associated with On; the actress was just announced as the company’s newest brand partner.

In this role, she will likely be responsible for creating creative ads spanning lifestyle, movement, and sports, as well as reimagining some of On’s current garment ranges. Federer is also an entrepreneur for On and has a line of tennis-inspired clothing with the company.
