Celebrity Big Brother star Kellie Maloney broke down in tears and dramatically threatened to quit the show tonight.
The former boxing promoter sobbed to her fellow housemates Lauren Goodger and White Dee that she felt "vulnerable" and feared she was "breaking up".
Maloney, who used to be known as Frank and managed ex-heavyweight champion Lennox Lewis, retreated to a corner of the house where she revealed she was struggling to cope under the constant glare of the cameras on the Channel 5 show.
Breaking down in tears she said: "I just can't handle it. I don't know. I've never felt like this, I've never felt so weak and vulnerable. I'm going to explode in a minute."
She added: "If they don't let me out I'm going to climb out tonight.
"I'm breaking up. I never had vulnerability before."
Former The Only Way Is Essex star Goodger and Benefits Street star White Dee quickly rallied round and gave the former boxing manager an inspirational pep talk to encourage her to stay.
White Dee told her: "But who are you now? Who have you reinvented yourself as? You are not Frank. You have traits of Frank.
"You have hidden Kellie for so many years. This is Kellie. Be Kellie. Be Kellie. It is not about you have never been vulnerable. You have never been Kellie. Be Kellie now."
Meanwhile Hollywood actor Gary Busey continued to rile up his fellow housemates, and got into another spat with former Will & Grace star Leslie Jordan.
The two stars eventually made up with a hug, but there continue to be concerns Busey is becoming increasingly isolated from his fellow housemates.
Broadcasting regulators Ofcom said they had received 206 of complaints from viewers worried about the welfare of the former Hollywood star, who had to undergo brain surgery after a motorbike crash in 1988.
Since his arrival at the house Busey has clashed with many of his fellow celebrities including former Strictly Come Dancing star James Jordan, Kelly Brook's fiance David McIntosh, and diminutive acting star Leslie Jordan.
And he suffered some more bad news when it was revealed that Leslie Jordan had been voted "star of the show" by viewers, giving him the power to exile to fellow housemates to the scrapheap in the garden.
He chose Busey and Angelique ''Frenchy'' Morgan. But Busey complained that he couldn't go outside because of the brain surgery he previously underwent.
Commenting on viewers' concerns about Busey's welfare, a Celebrity Big Brother spokeswoman said: "In accordance with standard procedure for CBB, the housemates are all independently evaluated before they enter the house and are closely monitored at all times."
