It was Simon Cowell who broke the news yesterday, in a statement that said: '"The worst kept secret in Hollywood is out. Mario and Khloé are our hosts. They will debut on our first live show in November and I couldn't be happier."
Both Khloé and Mario seem pretty happy about their new jobs too. Khloé wrote on her official website: "I’m a huge fan of the show so I literally fell over in my chair when I heard that I was being considered for the role.
"I’m thrilled, overjoyed and of course a little nervous about this new step in my career, and I can’t wait to get started!"
Mario Lopez - who previously hosted MTV's 'America's Best Dance Crew' - said pretty much the same thing, adding, "Khloé and I have been friends for years and I know we'll be a great team and have a blast."
Well that's all very nice. We can't stop ourselves hoping that Mario will made to walk out to the theme tune of Saved By The Bell every show, though. Is that mean?
What do you think about Simon's choices?
