Fifty Shades star Jamie Dornan hilariously describes awkward 'wee-bag' he wore during filming

Jamie Dornan has spilled on some of the more embarrassing parts about shooting the new Fifty Shades Freed film.

The actor revealed on Jimmy Kimmel Live! that he needed to wear a "wee-bag" while shooting some of the raunchier scenes.

But it's not what you think!

Jamie - who is from Ireland - quipped: "I wear a 'wee-bag'. Well, that's an expression from where I'm from - a wee-bag. But it doesn't mean it's actually wee in size. I wear quite a big bag! I wear this huge travel bag and stuff everything in there."

What he was trying to describe was a modesty pouch so that his genitals weren't completely on show, and he has joked that he needs a "huge" bag because his manhood is so big.

And, although he's been filming the blockbusters for three years, Jamie is still waiting to get his own pouch - also known as a c**k sock - as he's always had a second hand one.

He added: "I'd love to get to the stage where you have your own one that you get to carry around. I think I was right to think this way: On the first movie, there was a selection of them, and I picked one. I thought you'd take them out of the packets and they'd be brand new; they'd have that brand new smell. Then I sort of picked one that I liked the look of and the shape of, and in the seam it said, 'Inmate No. 3.' It was sewn into it. I was like, 'S**t. This has been used before?' When you picture the guy playing Inmate No. 3 in a movie in your head ... I don't know. It's not sexy!"

Jamie also teased his co-star Dakota Johnson over the amount of boyfriends she's had in the three years they've been shooting the Fifty Shades of Grey franchise.

Jamie portrays handsome S&M enthusiast Christian Grey in the erotic films, with Dakota playing his lover Anastasia Steele in the trilogy of erotic dramas, which come to an end with Fifty Shades Freed.

The 35-year-old actor - who is married to songwriter Amelia Warner - insists he and Dakota, 28, have a very sibling-like relationship and he has felt protective of her when it comes to the various men she's dated whilst they've known each other.

He told host Jimmy Kimmel: "This is going to sound bad, but it's almost like brother-sister. Because I am married and she's had quite a lot of relationships in the time that we've known each other, so that's happening in our own lives. You just sort of have this mutual love and respect for each other. I feel we know each other so well - intimately."
