50 Cent + Underwood Play Astronauts in New Ad

50 Cent and Carrie Underwood have teamed up with U.S. sports stars David Ortiz and Brian Urlacher to play trainee astronauts in a new energy drink ad.

The odd group portray rookies who are far more developed than their teachers in the new Vitamin Water ad campaign.

Rapper 50 Cent, who was a part-owner of the brand before Coca Cola bought Vitamin Water last year, knocks out a boxer in a sparring session, while Underwood raises a laugh when she refuses to resuscitate a passed out Russian instructor.
