Chelsea opened the interview by congratulating Piers on his new gig because it's a "Step up from America's Got Talent." From there, it continued to the eventual discussion of being replaced by David Hasselhoff and 50 Cent.
So, who is Piers' dream-guest? Chelsea's rumored-boyfriend 50 Cent (or as he put it, 50 Half-Dollar.) All in good fun, though!
