HOLLYWOOD -- Tyrese is going to the chocolate factory for his fourth album.

R. Kelly, who has worked with B2K, Nick Cannon and Baby already this year, has signed on produce the "2 Fast 2 Furious" star's follow-up to 2002's I Wanna Go There.

"He's the R&B king, man," Tyrese said recently. "R&B is what I do, and I'm just looking forward to taking a back seat and just getting whatever he's here to give me."

The album, tentatively due in December, will also include some production assistance from the Underdogs, whose résumé includes Justin Timberlake and B2K. The Underdogs also produced Tyrese's current hit, "Signs of Love Makin'."

"I'm really into hearing the women out, and they really are excited about zodiac signs," the singer explained. "They like to feel like they're connected to another zodiac sign, compatible with [someone]. And me being aware of this, I had to write about it."

Tyrese will spend the summer touring with Ginuwine and Lil' Zane beginning later this month. Kelly, meanwhile, will release his first greatest hits package, The "R." in R&B Collection Volume 1, on September 9. The album includes several classics, along with the new single "Thoia-Thoing," which just hit radio outlets, and "Ghetto Religion," which features Wyclef Jean.
