Maybe the C stands for crude.

Popular Hot 97 disc jockey Mr. Cee — who also produced Notorious B.I.G.’s first album, “Ready to Die” — was busted in TriBeCa for public lewdness after cops caught him in a car receiving oral sex from a male companion, officials said.

Police said Mr. Cee, whose real name is Calvin Lebrun, 44, was in a parked car last Wednesday when he was arrested at 4:05 a.m. with Lawrence Campbell, 20, at Watts and West streets, eight blocks from the radio station where he hosts the “Throwback at Noon” show that features classic hip hop.
