Ananova:

Hang on to your broomsticks kids.

Things are a-brewing down at Hogwarts.

And the spell is of a raunchy nature.

The word is that things got a little heated down on the set...

Two male streakers held up filming of the new Harry Potter movie - by darting naked through bushes during a woodland scene.

We know it's childish, but streakers always make us chuckle.

Clearly not keen to see the streakers' wares, Daniel Radcliffe and Helena Bonham Carter ducked off to their caravans while security chased the pair off.

But once filming resumed on The Half-Blood Prince, the nude duo crept back and made monkey noises at the location shoot in Farnham, Surrey.

The wee scamps...

A source told The Sun: "Seeing naked bodies was a laugh - but the joke wore thin."
