Heartthrob JESSE McCARTNEY is coming out with his third album, Departure this spring, and ET has a sneak peek at the video for his first single, "Leavin.'"

According to reps for his label, Hollywood Records, the album touches on everything from growing pains to interpersonal relationships. "Leavin'" was produced by hitmakers TRICKY and THE-DREAM, the creative forces behind RIHANNA's "Umbrella."

The 21-year-old multi-platinum recording artist has been nominated for two Emmys for his acting work -- his voice will be heard in theaters this Friday in the animated DR. SEUSS pic, 'Horton Hears a Who!"
