During a task in which housemates were asked to pair statements with which person it was about - the boys correctly guessed that Eileen had indeed starred in an adult movie - despite being under the age of 18 at the time.
‘I was very very young, I was under 18 and they sent me to Copenhagen. It was 1979’ explained the film director to her housemates.
The 51-year-old star has already been coined the ‘weirdest housemate ever’ on Twitter - which is saying a lot, considering some of the past contestants on the show.
Daly, who made a name for herself starring in films and adverts, says she’s ‘played about 10 vampires’ over the course of her career - so perhaps that’s where her obsession with looking forever young comes from.
‘I sometimes invite my girlfriends over on a Friday night and we give each other botox,’ Eileen shared in her VT.
We’d never have guessed...
Katie Hopkins had plenty to say as Eileen entered the house on Tuesday night, tweeting: 'Eileen: Do I look nervous? No darling, not nervous, or worried, or angry, or surprised. I don't think these are in your botoxed remit.'
She also compared the star to her CBB housemate Alicia Douvall who does bear a striking resemblance to the former plastic surgery addict.
