Later, Mister Cee worked as a radio personality for New York’s radio station 103.9 and Hot 97 morning show Ebro in the Morning.

Mister Cee made headlines on gossip blogs following multiple arrests for soliciting s3x from male prostitutes and transgender people.

After resigning from Hot 97, Mister Cee returned to the morning show to explain a viral video that ruined his career. He denied being gay when asked by Hot 97 radio host Ebro Darden.

“Have I lied about getting sexual fellatio in a car with a transsexual, yes,” Mister Cee said. “I have lied about that… Do I consider myself gay? No,” he said, before breaking down in tears.

Most recently, Cee could be heard on 94.7 The Block and Rock The Bells radio on SiriusXM.
