The housemates were taking part in their Superhero shopping task when the Geordie Shore star accidentally flashed her plentiful bust.
Some of the celebrities were asked to answer a series of questions honestly in order to win the house luxury food for the next week.
Jamie O’Hara was asked: ”Do you have feelings for anyone in the house?"
"Yes I do. I am starting to get very strong feelings for Bianca," he replied.
Chloe Ferry's ample assets fell out her top whilst Jamie O'Hara confessed he likes Bianca Gascoigne

It’s alright darling. I’ve seen them before, don’t worry
As the housemates cheered at his declaration, 21-year-old Chloe went to hug Bianca Gascoigne when she ruined the sweet moment.
Her breasts appeared to pop out from her blue superhero outfit.
Bianca seemed to find the incident more interesting than Jamie as she burst into laughter, whilst the Geordie lass fell on the floor in hysterics.
When Chloe eventually calmed down she kept on apologising to Game of Thrones star James Cosmo.
But, he assured her: “It’s alright darling. I’ve seen them before, don’t worry.”

Later in the episode, Chloe turned up her unruly antics up a notch as she was seen giving Jedward’s John Grimes a seriously sexy lap dance.
The scantily-clad beauty was wearing a sequinned two-piece bikini when she straddled him, and bounced up and down.
Her latest actions come after she was called into the Diary Room for being warned of making “uninvited physical contact” when she rubbed her bare bottom on the Irish twin earlier this week.
Celebrity Big Brother continues tonight on Channel 5 at 9pm.
