(Cover) - EN Showbiz - Ryan Gosling and Eva Mendes are acting more naughty than nice this Christmas.

The loved up couple showed off their comedic chops for a hilarious new Funny or Die video entitled Drunk History Christmas.

In the clip, comedian Allen McLeod drank half a bottle of whiskey before reciting the classic poem, Twas the Night Before Christmas, as Eva and Ryan act out the parts with Jim Carrey starring as Santa.

The lucky actress got to cosy up in bed to her real-life boyfriend as they play a married couple with two children who are settling in for the night before the big day.

The profanity-laden version of the famous poem starring the new Hollywood couple shows that they are happy going public with their romance.

The two stars began dating earlier this year and spent the recent Thanksgiving holiday in Paris together. They were seen cuddling up as they explored the famously romantic city and Ryan apparently feels totally at ease with his new love.

The actor has already started confiding in friends that he believes they will be together forever.

"Ryan is telling everyone that he's very serious about Eva," a source told In Touch magazine.

"He is head-over-heels and plans to settle down with her. Ryan doesn't take dating lightly. He falls in love very deeply." (C) Cover Media
