James Corden loves hosting 'The Late, Late Show' because he gets to ''be an idiot'' every night.

The chat show host still can't believe he is hosting such a huge show in the US and can't wait to see where the next year takes the show.

He said: ''Historically, these shows start bad and get better. So I'm excited to see where we are in a year. That gets the fire in my belly.

''Like, we're making a proper show on American TV. If I could tell my 12-year-old self that this would be my life right now, his head would explode. I'm an idiot and I just get to be an idiot every night.''

And though his new approach to the traditional format has been praised, the British host insists it simply conceals his short-comings.

He told GQ magazine: ''It's not so much as playing to my strengths as hiding my weaknesses.''

The 37-year-old star - who has children Max, four, and 10-month-old Carey with wife Julia - admitted his hectic schedule on the late-night show has left him exhausted.

He admitted: ''I actually don't even know how tired I am right now.''
