She may have bade farewell to Hermione, but Emma Watson can still cast quite a spell.

The beguiling Brit's latest victim is chat show host and comedian, Jimmy Fallon, who danced up a storm with the Harry Potter star on his show last night.

This included jazz hands from Singin' in the Rain, the carnival sequence from Grease and the Dirty Dancing lift.

Later she tweeted: 'Danced with [Jimmy Fallon] tonight. #anotherboxticked.'

The Perks of a Wallflower is a coming-of-age story based on the bestselling novel by Stephen Chbosky, and sees Emma star alongside Logan and Ezra of We Need to Talk About Kevin fame in the story of an introvert freshman who is taken under the wings of two seniors.

Emma plays the role of Sam, Patrick's (played by Miller) free-spirited step-sister, whom Charlie (played by Lerman) falls for.

What a hoot: The stars obviously enjoyed performing with one anotherTalking about the movie recently, Emma said she is hoping it allows her fans to see a different side to her, rather than her Harry Potter alter-ego Hermione.

She said: 'I hope what Harry Potter fans can see is that I am able to transform, that there are other sides of me that perhaps they haven't seen yet, and that they might allow me a little bit of room.

'Just doing American really is different. People have said to me that they keep forgetting it's me when they see the movie, which for me is more than enough. That's a success in itself for me, really.'
