VIDEO: Listen to Adam Levine, Gwen Stefani Duet on Maroon 5's 'My Heart Is Open'

In addition to facing off as opposing coaches on NBC's THE VOICE, Adam Levine and Gwen Stefani are teaming up for a song on Maroon 5's new album "V." The song, "My Heart Is Open," is available now on iTunes, but you can listen now below.

Maroon 5 guitarist James Valentine told Billboard Magazine, "It's cool for all of us to have [Stefani] on the record, and Adam won't shut up about how cool she is as a person. A lot of times when you meet your idols it's a letdown, but it's the opposite case with Gwen, apparently."

"V" "drops" on September 2nd.
