Mindless Behavior [1] will release its sophomore album in January 2013, Billboard.com has learned.

Mindless Behavior: 21 Under 21 (2012) [2]

The as-yet-untitled set, the follow-up to 2011 debut "#1 Girl," will include several collaborations, including one with Soulja Boy.

The Interscope quartet's debut peaked at No. 7 on the Billboard 200, reaching No. 2 on the R&B/Hip-Hop Albums tally. After touring stints with Janet Jackson, Justin Bieber and others, they embarked on a headlining tour of their own this summer.

"The second album is going show everyone that we're not kids anymore," singer Princeton previously told Billboard. "We're teenagers. We're a boy band, but we're not kids."

But the group has more than music up their sleeves: per their label, they're currently in production on a film, also due in early 2013.
