R&B vocalist Omarion will release his sophomore album, "21," Oct. 31 via Epic. The set features production from Pharrell Williams, the Underdogs and Bryan Michael Cox. First single "Entourage" is No. 27 this week on Billboard's Hot R&B/Hip-Hop Songs chart.

"To me, at 21, it was a realization of who I wanted to become -- just me practicing my morals as a man and getting better in my craft," Omarion says. The album is the follow-up to 2005's "O," which debuted at No. 1 on both The Billboard 200 and Billboard's Top R&B/Hip-Hop Albums chart.

Omarion will also be seen in several upcoming films, including the horror movie "Somebody Help Me," which also features fellow R&B artist Marques Houston. Next up is "Reggaeton," about an aspiring Bronx rapper forced to flee to Puerto Rico, and the drama "Street Soldier."

Here is the track list for "21":

"Entourage"
"Have You Ever Been With a Star"
"Electric"
"The Truth"
"What Are We Doing?"
"Midnight"
"Do It"
"Impossible"
