Budding music star Leighton Meester has already had a great summer with her guest vocals on the hit Cobra Starship track “Good Girls Go Bad.” Now, after various leaked tracks popped up on the Internet, the actress is finally debuting her first official single, “Somebody to Love.”

The Gossip Girl star has been hard at work on her solo album, which she hopes to release before the end of the year, while dividing her time between the GG set and filming the 2010 thriller The Roommate. The sexy electronic-tinged track finds Meester dueting with Robin Thicke, whom Meester says she absolutely adores. “He’s so soulful, and his voice is so flawless and beautiful,” gushes the actress. “I don’t even think he knows how much I love him.”

Meester also says the track’s theme of searching for true love is something she personally struggles with. “I so often get love confused with sex and vice versa. And the song is basically about how I can’t get any—I can’t find anyone to love.”
