Jack faced the harshest criticism from his co-stars during the first round of nominations.
He was picked by comic Donna Preston for wearing too much aftershave, and by Towie star Ella Rae Wise for having "a game plan".
EastEnders star Patsy Palmer accused him of "looking like The Joker" in the dark and said it terrified her.
Trisha Goddard chose Jack because he behaved like "a snake" - saying he sits quietly before "biting" - while Danny Beard said the actor told jokes to offend rather than get a laugh.
Nineties pop fans will be excited that Chesney Hawkes is in the Big Brother house, but did you know:
He grew up in a rock’n’roll household. His dad, Chip, was a musician; his mum, Carol [Dilworth], was an actress and gameshow hostess. He says: "They were glamorous. They had famous friends. Our house was always party central."
He once said that growing up withguitars propped in every corner and a little recording studio in the house meant that "my brother, sister and I were never going to become accountants".
He admits to being "quite a precocious kid. I never had any other aspirations other than music, so I slightly rebelled at school. I wish I’d paid more attention. I left at 15 and learned my craft by playing pianos in pubs."
She told The Sun: “We are not together. And it's really, really sad that we're not together. We split up a week ago.
“It has nothing to do with Big Brother. It was a decision that I had to make because I didn't feel that we were getting things that we wanted out of each other.
“We can be best friends, but if something's missing, what are we wasting our time for?
“I just feel that he's very set in his ways and I can't change someone and I can't expect someone to change either.
“And if he's comfortable in how he is and if he thinks what he gives in a relationship is enough, that's okay because that can be enough for someone.
Watch: Mickey Rourke 'weight shames' Donna Preston
Mickey Rourke is in trouble again after "weight shaming" Celebrity Big Brother housemate Donna Preston.
Hours after he got a formal warning for upsetting JoJo Siwa by using a homophobic slur, The Wrestler star left Donna stunned when he made a strange remark in the bedroom.
Watch shock moment Mickey Rourke 'weight shames' Donna Preston just hours after formal warning over homophobic slur
With episode four on our screens tonight at 9pm, here is a recap of what's happened since launch night on Monday:
Mickey Rourke faces a real chance of being kicked out at the first formal eviction on Friday – if not before – following his behaviour against fellow housemates JoJo Siwa (homophobic slur), Donna Preston ('weight shaming') and not forgetting his "pervy behaviour" towards host AJ Odudu even before entering the house.
Michael Fabricant has opened up about his sexuality to Jojo and Danny Beard.
Trisha Goddard – who is living with stage four cancer – has been given her own bedroom.
Mickey Rourke snores ... like a steam train.
Ella Rae Wise broke down in tears after she opened up about her split from Dan Edgar in emotional scene.
Ella and Chris Hughes were spotted flirting just minutes after arriving in the house before sharing a hot tub.
During tonight's show, the housemates will gather in the living room to cast their vote on who they want to leave the house but Mickey will be reprimanded over his remarks.
In another rule break, Mickey says to Big Brother: “I choose not to evict anyone.
"I refuse to do that. I will not pick two people to toss off the shelf.”
Big Brother then once again reminds Mickey of the rules.
Donna has chosen to nominate Jack for 'going overboard on the aftershave' and Angellica because she 'felt deflated' they wore the same pyjamas.
Chesney has chosen Jack because he's 'quite standoff-ish' and Donna because her missing her own family is reminding him of his.
Patsy has nominated Jack because he 'looked like the Joker' when she woke up beside him and she fears she could have nightmares. Her second choice is Michael because she feels he 'ignores her'.
Danny has picked Jack over his jokes and says how he 'enjoys messing with people's minds' and Chesney as he's not as close with the hitmaker.
Finally, Trisha has nominated Michael over his 'overwhelming stories' that leave her 'for dead'. Her second nomination is Jack - because of his dark sense of humour.
The former MP has nominated Patsy over her questioning why he wears a wig - admitting he doesn't like his hair being raised in conversation as it's his 'sensitivity'.
His nomination is Ella - as she's the one he's least spoken to in the spy house.
As ever, Celebrity Big Brother fans have flooded social media with their take on tonight's scenes.
One posted: "Mickey is either deep, offensive or asleep.. nothing less or more."
A second wrote: "Patsy is just so beautiful."
"I'm sorry but how on earth can he have insomnia?! All he's been doing is sleeping, I do kind of feel bad for him though after his thing about having no confidence," said a third.
