Former Big Brother winner Helen, 27, took to Twitter to blast Chloe, 21, after 34-year-old Jeremy was removed from the house.
She wrote: "Well done @Chloe_Goodman you've basically just ruined a guys life by those actions, the sh*t he is going to get. Great move. #CBB [sic]"
After Chloe tried to help a drunk Jeremy to the bathroom, she insisted the actor groped her.
Speaking to her other housemates, a tearful Chloe said: "I was helping him and he literally just [opened] my dressing gown top and took my boob out."
Jeremy was called to the diary room where he initially claimed he wanted to see what Chloe was wearing under her dressing gown.
He said: "She was in a robe, I'm drunk… I thought she had a bathing suit on underneath. I didn't touch her body. I made a mistake. I didn't think she was naked underneath… curiosity killed the cat."
However Big Brother told him: "The rules of unacceptable behaviour were explained to you. Last night while alone in the toilet you deliberately opened Chloe's dressing gown."
Jeremy later accepted what he'd done, saying: "Besides apologising and insisting it was not aggressive, no I accept all ramifications."
