Her Hollywood Resume: She's done 2007's The Haunting of Sorority Row, 2008's Killer Movie and...ah, who are we kidding? This is the hot brunette chick from Gossip Girl. That's all you need to know.
Her Musical Efforts: Her claim to fame musically is a guest appearance on Cobra Starship's 2009 pop hit, "Good Girls Go Bad." But she's also got a pair of her own singles (including 2009's Robin Thicke-assisted "Somebody To Love") and a debut album, Love Is a Drug, in the works for 2011.
How Well She Crossed Over: It took us about six months to realize that "the hot brunette from Gossip Girl" was the chick singing on Cobra Starship's song. But once we did, we were impressed enough to want to hear more. Hopefully she delivers.
