She's known for her brazen and unruly antics in the Geordie Shore house.

And Chloe Ferry, 21, brought a taste of that behaviour into the CBB compound on Tuesday when she backed her bare bottom up against John Grimes as he rooted around in a cupboard underneath the sink.

The Jedward star got a shock as Chloe emerged from the shower in a pink towel only to lift it up to reveal her derriere.

Jedward escaped eviction on Tuesday, with the public voting to save the twins and James Cosmo at the expense of James Jordan.

During the face to face nominations, James had a heated exchange with Jedward, telling them to 'shut the f**k up'.

In his exit interview, the pro dancer said that the duo had a massive following so he wasn't surprised they were voted to remain in the house.
