Corden jokes had Swift in stitches
Taylor Swift has been singing James Corden's praises, saying she couldn't get enough of his sense of humour when she met him.
The I Knew You Were Trouble singer was promoting One Chance with James, which he stars in as Britain's Got Talent winner Paul Potts, as she features on the soundtrack.
She told The Sun: "Doing press with him is the funniest thing you can do. He never stops making you laugh. There was a cast photoshoot at the Toronto Film Festival. There was not one photo of me where I keep a straight face because James was standing next to me.
"He kept saying these hilarious things and I couldn't keep it together, not even for one picture, it was hilarious."
Taylor, 23, also said she thought that One Chance could be James's break out film in America.
She said: "James's performance is going to be the stand-out moment of his career. It will make more people aware of him, especially in the US. People are going to fall in love with him."
