Leighton Meester, star of the CW Network's teen drama "Gossip Girl," has signed a deal with Universal Republic through Time-Act Music to release her debut album in the fall. The 23-year-old actress began recording material-- described as having an "electro-pop edge"--for the project in March and has clocked studio time with producers Polow Da Don (Usher, Fergie), Harvey Mason, Jr. (Justin Timberlake, Pink) and Spencer Nezey (Jupiter Rising).

In addition to her role on "Gossip Girl," Meester starred in 2007's "Drive Thru" and performed a duet with Tony Bennett during a 2008 return guest appearance on HBO's "Entourage." She is lined up for two films in 2010: Sony Screen Gems' "The Roommate," a suspense thriller directed by Christian E. Christiansen, and 20th Century Fox's upcoming comedy, "Date Night."
