Cameron Diaz and Colin Firth admitted they had a blast filming 'Gambit' together as they walked the red carpet at the film's world premiere.
The A-list pair were dressed to the nines with Colin, 52, looking smart in a well-cut suit and 40-year-old beauty Cameron glowing in an elegant black and white Stella Mccartney dress.
However, 'The King's Speech' actor Colin's biggest worry in the film was his lack of clothing thanks to a scene in which he wore nothing but a shirt.
He told BANG Showbiz: ''I did have a bit of leg anxiety at the time. It's one thing to basically drop everything, but just the trousers ... It's just not a look that's recommended for a gentleman - brogues, socks up to the knees, underpants!''
The handsome actor had fun filming with Cameron Diaz, and says she always brought her sense of humour to the set, even during his most embarrassing scenes.
Colin added: ''It's been fabulous, she's the best at what she does. There were plenty of funny moments on set. [I mean], If you have to walk with your trousers off through the lobby of the Savoy Hotel...''
