Dakota: My Fifty Shades bum secret

DISHY Dakota Johnson says she used an ARSE double to film kinky Fifty Shades Of Grey.

Despite baring all for most of her debut lead role, the 26-year-old actress admitted she used a stand-in when it came to saucy spank scenes.

The brunette babe told how she was not up for the S&M punishments with her co-star Jamie Dornan because she couldn’t handle the pain.

She said: “There was a close-up of a bum getting hit with a belt. That was not my bum, because I didn’t want to get hit with a belt.

“I couldn’t turn down the opportunity – I wanted to be involved because it’s so different and it’s an intense love story.”

Meanwhile the Texas-born star opened up on how men don’t approach her because of her recent racy role.

She added: “Some people think this is something I’m interested in, in my private life, which is not the case.”
