Trina is hard at work on her fourth album, Baddest B*tch II, due Dec. 19 via Slip-N-Slide/Atlantic.

Although guest features have yet to be lined up, the disc will boast production by Kanye West, Scott Storch, Jazze Pha, Cool & Dre, Swizz Beatz and Just Blaze.

Among the rapper's upcoming collaborations is a track she recorded for Black Eyed Peas singer Fergie's solo debut, The Dutchess. "The song is really hot. It's an up-tempo record with a fast, bouncy beat," Trina tells Billboard.com.

In addition, the rapper will release her second as-yet-untitled fragrance to follow up Diamond Princess by Trina, and in December, she will offer a sneak peak of her new clothing line DP Wear (Diamond Princess Wear).

"I've been working on it for awhile and trying to get it to be right and to be presentable," she says of the venture. "I don't want to just put something out there that doesn't represent me. I want something I would wear."
