She's used to causing a stir - most frequently thanks to her revealing outfits.

But Myleene Klass stunned for another reason on Thursday night as she showed off her double-jointed arms on Celebrity Juice.

The mother-of-two demonstrated her 'skill' to the rest of the panellists on the ITV2 show, including Holly Willoughby, Kelly Brook and Dave Berry.

'That's not normal!' Myleene Klass showed off her double jointed arms on Celebrity Juice on Thursday night

Bending her arms the wrong way at the elbow, Myleene grinned with delight as her celebrity co-stars shrieked in horror.

Holly could even be heard in the background saying: 'That's not normal, Myleene!'

Explaining her bizarre ability to host Keith Lemon, Myleene said: I'm hyper extended. What it means is that your joints just bend further than everyone else's. But if I lean, they just kind of click about.'

Party trick: Myleene demonstrated her skill to her fellow celebrity panellists, much to their horror

And asked how she first discovered the ability, Myleene replied: 'I was in a P.E. class. I remember the teacher came over and told me I wasn't trying hard enough, she said my arms weren't bending enough.

'So she came over and pushed my arm down, and everyone thought I'd broken my arm!'

Capital FM Dave then asked Myleene if she was hyper extended in her legs as well, with the presenter replying: 'A bit, yes!'

Back to work: Myleene hosted the Natwest UK Fashion and Textile Awards on Thursday night

Careful! Myleene struggled to make her way down the stairs in the heels after the event

The cheeky chappy then replied: 'Nice!'

Myleene previously revealed that her hypermobility means that she is able to play the piano backwards.

But it wasn't the Juice panellists that were left stunned by Myleene's party trick - viewers were quick to take to Twitter and comment on the bizarre ability.

One wrote: 'Myleene Klass is stunningly beautiful but that thing she just done with her arms is freaky.'

And another added: 'Makes me feel sick when myleene does that thing with her arms #celebjuice.'

Myleene herself later wrote on Twitter: 'Just fin work. Hear my 'bendy arms' have freaked most of you out on @celebjuice! Mwah ha ha.'
