Lil Jon is taking his new Celebrity Apprentice gig very seriously! The “King of Crunk” hit the streets of Manhattan Tuesday (Oct. 19) to hawk pizza for charity.

Lil Jon was spotted holding a poster board outside of Famous Famiglia Pizzeria for a taping of Donald Trump’s “Celebrity Apprentice,” and he was joined by his fellow castmates John Rich, David Cassidy, Mark McGrath, Richard Hatch, Gary Busey, and Meatloaf.

LJ knows how to get a crowd crunk and I’m sure he’s sold a helluva lot of pizza pie! Check out more photos + video of Jon’s salesmanship below:

Lil Jon, Busey and Rich stood outside the pizzeria and held up signs promoting the sale of the “celebrity” pizza, with the proceeds for each pie going to charity. At one point, the rapper and the country singer performed an acoustic rendition of Sugar Ray’s best-known song, “Fly,” to draw support, with Lil Jon telling one fan, “Don’t just take a picture – pull out that credit card. Brother, you can make it rain!” Busey, meanwhile, talked casually with onlookers and referred to himself as the “pepperoni prophet.”

Inside the restaurant, Meat Loaf manned the register as McGrath flipped pizza pies for smiling customers. Baseball star Jose Canseco, “Survivor” winner Richard Hatch, and David Cassidy were among the other celebrities helping out with delivering the orders.
