Nick Cannon and Chelsea HandlerWhen Nick Cannon and Chelsea Handler had a much publicized Twitter feud back in October, many thought it was because of a wisecrack Handler took at the expectant father. But to hear Cannon tell the story, it all started with comments the comedian made about his wife, Mariah Carey.

When Handler tweeted the joke, "I just heard Nick Cannon is starting a comedy tour. Who's going to do the comedy?" it resulted in an onslaught of replies from Nick Cannon, including a rather controversial tweet calling Handler, Eminem and Howard Stern "ugly white trash."

The two eventually cleared the air and spoke in person when Handler called into Cannon's radio show. Speaking this morning to John Katsilometes on the radio show 'Kats With the Dish,' Cannon revealed a few more details about the spat.
