Miley Cyrus' mysterious new music video project has just been released -- and ET has it!
Miley stars opposite "Gossip Girl"'s Kevin Zegers in Rock Mafia's "The Big Bang" music video.
"Rock Mafia is my family and there's nothing that means more than creating with them," said Cyrus. "The video is unique and honestly, was a life-changing experience. This song means a lot to me."
"The Big Bang" single is now available on iTunes for download.
