<i>Fifty Shades of Grey</i>'s Jamie Dornan sick of tying up women!

Northern Irish actor Jamie Dornan has learnt some valuable lessons from playing S&M master Christian Grey in the upcoming movie adaptation of the erotic bestseller, Fifty Shades of Grey.

One such skill is tying knots — but he's already over it!

"There are a couple of classic knots I know now," the 31-year-old told The Guardian. "And I've put them to good use far too many times recently. In fact I'd like to do a job where I don't have to tie women to beds."

The woman in question is Dakota Johnson, Melanie Griffith and Don Johnson's actress daughter, who plays his love (and sex) interest Anastasia Steele.

But it's not all fun rope play for former underwear model Jamie. In his next project, Jamie plays serial killer Paul Spector in the BBC TV crime drama The Fall.

"The role also requires some knot-play but this time, it's not for fun — it's for murder," Jamie added.

Uhh, way to spoil the whole Christian Grey aura, dude.

Sadly for die-hard fans, the buff star is married to musician Amelia Warner, who gave birth to their daughter in November 2013. The pair has kept the bub's name secret for six months already… maybe they called her Anastasia? We'll keep you posted as soon as we know, FIXies.

"I've done three jobs back to back," Jamie said. "Let's see how they are received. If there's nothing I want to do, I'll just play golf and change [diapers]."

Rope-work and changing nappies... is there anything this heart-throb can't do?

Fifty Shades of Grey is due for release February 12, 2015. Vote 'want to see' or 'not interested' on MovieBuzz now.

Last month, a fan-made trailer went viral featuring footage of the lead stars in previous sexy roles. Watch below, it's quite the tease indeed!
