"I only know the guy parts so that puts you in an interesting position" is how Gosling prefaced his dance class with Fallon, making men and women around the world swoon in the process.

There's many a human that would give an arm and a leg for Ryan Gosling's forefinger and thumb to "start talking" to their lower backs and last night it was Jimmy Kimmel who has that honour bestowed upon him.

Gosling was on the show to talk about his upcoming musical motion picture 'La La Land', which features plenty of him and Emma Stone dancing and singing away to their heart's content, so it was only natural that Kimmel get a lesson from Hollywood's and the world's favourite leading man.

Turns out he's quite the strict teacher, and even Kimmel struggled to keep his cool.
