Showing off his diamond-studded grill, Lil Wayne was busy filming on the set of the new Mack 10 music video So Sharp in Malibu yesterday (June 1). The video is directed by K.C. Amos and features Rick Ross and a bunch of bikini-clad video girls. How original.

Meanwhile, the Prom Queen rapper has reportedly recorded 12 songs with T-Pain for an upcoming joint project.

T-Pain tells MTV News that the recording process was “going slow” but that there was “no rush” to finish their work, which he has dubbed T-Wayne.

“It can come out whenever. We’re gonna keep it pushing, however. It’s gonna be pushed,” he says.

The duo originally announced their partnership last July, when T-Pain said: “T-Wayne is an entity that’s just gonna take over. It’s two artists that are done collaborated with every artist in the industry except each other.”
