Piers Morgan, the new 9pmET host on CNN, and Larry King, the longtime CNN 9pmET host who came before, discussed some recent comments King made on BBC Radio 4. Was Piers "oversold"? Is he really as "dangerous" as the promos say?

The two discussed "Piers Morgan Tonight" so far, as well as the meaning of "dangerous." "I'm from Brooklyn," said King. "If you say 'I'm dangerous,' you better be dangerous." In the end though, King joked that Piers was in fact dangerous after Piers told him suspenders in the U.K. actually mean quite a different thing than they do in the U.S. Video below: FULL POST

On last night's "Piers Morgan Tonight", Piers Morgan interviewed Hugh Hefner, his fiance Crystal Harris and Hef's son Cooper Hefner. During one portion of the interview, the subject of Justin Bieber came up. Hef said he took Crystal to see Bieber's new movie, and later revealed the teen pop star has asked to come to the Playboy Mansion – with his dad.
