WATCH THE 'FIFTY SHADES OF GREY' FULL TRAILER

For us, it's the excitement of watching the first full length trailer of the film adaptation of the best-selling erotic novel Fifty Shades of Grey that's making us twitch. For Christian Grey and Anastasia Steele, it means a whole lotta something else. *wink*

After much anticipation -- and a reworked version of Beyoncé's 'Crazy In Love' alongside a sexy 15-second tease of the trailer (below) -- the full version is finally here and it's naughty.

Think stolen glances, shared moments, first kisses and much, much more.

'Fifty Shades of Grey' will be in cinemas Valentine's Day 2015.
