James Corden has said he is "gobsmacked" by the success of his new show The Late Late Show with James Corden as he was expecting it to be "torn apart".

The 36-year-old TV presenter and actor began hosting the show in March and told Heat magazine that he didn't expect it to be a success.

Corden said, "I was so braced for the show to be torn apart that I'm gobsmacked by how quickly people have taken to it.

"And it's amazing to be able to sit with people like Tom Hanks and Will Ferrell and just be in their orbit for a bit."

He added that all of his guests so far have been down-to-earth, "No one has turned up with an entourage yet. Mila Kunis showed up with three people - her make-up artist, stylist and assistant, which seems fair enough.

"Mariah Carey was fantastic [when she did carpool karaoke]. With someone like her, who is such a megastar, you almost forget she's human and we really showed the human side of her. It was so much fun."

The star, who moved with his wife Julia and children Max and Carey to Los Angeles to work on the show, added that he feels like he's on holiday, "It still feels like I'm on holiday here. In no way have I taken on board that this is my job - I still haven't really adjusted to the fact that this is where I live now.

"But it turns out it's a really lovely place to be with the kids. The main thing is I miss my wider circle of family and friends. But at least I have a good supply of marmite."
