Selena Gomez & Nick Jonas: Wiffle Ball Buddies

Selena Gomez plays a game of wiffle ball with ex-boyfriend Nick Jonas on the set of their new music video, “Send It On,” at Pepperdine University on Saturday (June 6) in Malibu, Calif.

Also spotted: The two older Jonas Brothers were there as well — Kevin and Joe — as well as Nick’s other ex Miley Cyrus and her BFF Demi Lovato.

The song “Send It On” is part of Disney’s “Friends For Change: Project Green,” a multi-platform environmental initiative that invites kids to join together to help the environment across four key areas: climate, water, waste and habitats.
