The Black Eyed Peas have teamed up with Tom Cruise to produce the theme song to Cruise’s next movie Knight and Day which also co-stars Cameron Diaz. At BEP’s concert in London this past weekend, Will.I.Am brings Cruise up on stage to introduce the song called “Someday.”

“It’s just a perfect match, the perfect film for it,” Cruise told ABC’s “Good Morning America.” “The music is incredible. … You feel incredible at the end….We showed [will] some scenes, and he just started writing the song right there in the room.”

Knight and Day hits theaters June 25th.
