You’ll never guess which actor Emma Stone thinks is a ‘toolbag’!

Emma Stone evidently doesn’t think too much of the charms of one Colin Firth.

The actress appeared on the Late Show with David Letterman where she revealed what she really thinks of her Magic in the Moonlight co-star.

When David says: “He’s a tool,” Emma agrees, saying: “He’s a nightmare … he’s a toolbag.”

Hmm, we’re sure Emma was just joking…hopefully!
