Kevin Hart says Justin Bieber likely cried at Comedy Central Roast

LOS ANGELES, March 18 (UPI) -- Kevin Hart thinks he saw a tear form in Justin Bieber eyes during his Comedy Central Roast on Saturday.

The 35-year-old actor was the master of ceremony at the event where the likes of Ludacris, Jeff Ross, Snoop Dog and Martha Stewart poked fun at the Canadian pop star.

"It went a little rough, I'm not going to lie," Hart said of the comedy special.

"There were some moments where I was like, 'Justin's gonna cry in the car.' There's no way that he's not going to cry," he said.

Hart said at point he pointed at Bieber trying to encourage him.

"You don't let them cameras see it come down." he said, "He did one knee slap where I think he covered up a cry."

The Roast of Justin Bieber was pre-taped on Saturday and will air on March 30. The special has generated much buzz this week over Bieber addressing his past behavior and the jokes made at the expense of the late Paul Walker and singer and actress Selena Gomez.
