Former boy band member JC Chasez has worked with Justin Timberlake to record the new track "Until Yesterday," which deals with some very adult themes. The song, according to Chasez, is about "your girlfriend getting knocked up by another man." Timberlake worked with Chasez producing the song, after the two had been hanging out one night and decided they should work on a track together.

Chasez insists the song is not autobiographical, adding that he just wanted to push the limits of listeners.

Fans can expect a new album in February or March, according to Chasez.
