This is the first single from Timbaland's third studio album, Shock Value II.

The song features the seductive vocals of French-American singer SoShy, who is a recent signing of Timbaland's Mosley Music Group. Frequent Timbaland collaborator Nelly Furtado also contributes a verse.

Timbaland told MTV News that the song was inspired in part by the popular vampire franchise, Twilight. He said: "The song, I can't describe it, it's so different. It's not different for me, but I can tell you this - it fits everything going on with the vampire theme. It fits everything with Twilight."

Featured artist SoShy (real name Deborah Epstein) was born in France to a French-Argentine-Italian mother and French-Russian father, She split her childhood between Los Angeles and New York City. Timbaland told MTV News: "She's like Amy Winehouse to the 10th power. But not crazy. Sane. Not saying Amy Winehouse is crazy; she's ambitious. Soshy is ambitious, but she has a point to prove."

Two more pieces of SoShy trivia:
1. She co-wrote "Lost Cause" for alternative rock/pop artist Chris Cornell on his 2009 album Scream.
2. Her single "Dorothy" is featured on the FIFA 10 soundtrack.
