NEW YORK (AP) - Clearly, former CNN prime-time stars Larry King and Piers Morgan aren't big fans of each other.
After King derided Morgan's interview skills and called him pompous, Morgan responded on Twitter on Friday that King was a "graceless, petty little man." Morgan's 9 p.m. CNN show was canceled this year. He had replaced King in that time slot in 2011.

King, in an interview with WGRF in Buffalo, says he had trouble watching his successor because the interviews were all about him.
Morgan, in turn, criticized King's ratings, posting a clip where King famously misidentified addressed Ringo Starr as "George," and writing, "Get over it, you daft old goat."
