'Extra' Interviews Piers Morgan

CNN's debut of "Piers Morgan's Tonight" drew an impressive 2.1 million viewers with its Oprah Winfrey interview on Monday -- a strong opener for the new guy in town.

"Extra" visited with Piers and discussed which big-name celebs we can expect to see, and it seems he's booked the man of the moment, telling us, "Ricky Gervais [will appear] the first week, Simon Cowell's gonna come on -- he and I have been friends 20 years, we know where all the bodies are buried. He knows I'll be going there, so he'll be trying to hide the bodies."

"Piers Morgan Tonight's" premiere season will also include interviews with former NYC Mayor Rudy Giuliani, former Mass. Governor Mitt Romney, Kid Rock, and reality stars Kourtney and Kim Kardashian.
