The 34-year-old actor portrays sex obsessed billionaire Christian Grey in the 2015 erotic thriller and the upcoming two sequels and the first movie in the franchise made him a global superstar.

However, Jamie's songwriter spouse Amelia Warner doesn't know what all the fuss is about because she has never seen him get hot and heavy with his co-star Dakota Johnson - who portrays Christian's lover Anastasia Steele - in the movie.

When asked on the upcoming episode of 'The Jonathan Ross Show' how his wife feels about him playing such a sexy character with so many nude scenes, he replied: "My wife is one of the most brilliant human beings in the world. She hasn't watched it. Why would she watch it? She wouldn't put herself through that."

Jamie - who has two daughters with Amelia - has been busy filming the two sequels, 'Fifty Shades Darker' and Fifty Shades Freed', back-to-back.

The second film is to be released worldwide next Valentine's Day (14.02.17) but he remained tight-lipped on whether he gets naked on screen.

He said: "I haven't seen it so I don't know ... I don't even know. I don't know where the cameras were, I don't bother myself with that, I just get on with it. At times you are..."

But stripping off is not something he cares about.

He said: "I don't really care about that sort of stuff. I'm not nudist beach guy but I don't really mind."

'The Jonathan Ross Show' airs on Saturday (24.09.16) at 10:20pm on ITV.
