FROM hot tub romps to toilet trysts, Celebrity Big Brother has seen its share of scandalous hook-ups over the years.

As the show prepares to return for the first time in six years, it remains to be seen whether romance will blossom between any of the latest housemates.

The full line-up includes Glamorous Love Island winner Ekin-Su Culculoglu and former X Factor judge Sharon Osbourne who signed up for a huge sum.

Ahead of the ITV reboot on Monday, we take a trip down memory lane to celebrate CBB’s raunchiest moments.

Lewis Bloor and Marnie Simpson

These two couldn’t keep their hands off each other during their stint in the house in 2016.

One night Geordie Shore star Marnie and ex-Towie hunk Lewis stripped off for a saucy shower – and weren’t shy about emerging completely naked.

The full-frontal scenes shocked fans, with the episode in question receiving 54 complaints.

Lewis later claimed “nothing happened” between him and Marnie, but admitted: “I was horny.”

The couple continued dating after the show, but their romance ended months later.

Marnie, who is now happily married to former X Factor contestant Casey Johnson, recently told the Saving Grace podcast: “[CBB was] the easiest money I’ve ever made.

“All I did was smoke fags and sleep. But obviously I had a really public relationship in there and it ruined my time in there a little bit.”

Stephen Bear and Chloe Khan

On the same night as Lewis and Marnie’s sizzling shower, reality star Stephen Bear got hot and heavy with X Factor’s Chloe Khan on the sofa.

Viewers were convinced the pair then sneaked off to the bathroom to have sex away from the cameras, with some suspicious sounds emanating from the toilet.

But Stephen – who was dating Ex on the Beach star Lillie Lexie Gregg at the time – dismissed suggestions he went all the way with Chloe, claiming: “Nothing happened, we were just kissing and her boobies are massive!”

The couple were also seen together in the bath tub before moving on to the bedroom where they pulled the covers over their heads – much to the ire of their sleeping housemates.

Yet another housemate who conveniently forgot about her relationship outside of the house was Hollyoaks actress Stephanie Davis.

Despite being in a relationship with model Sam Reece, she infamously cracked on with a different model – Dubliner Jeremy McConnell.

The fiery pair brought a lot of drama to the house in 2016 and often were at each other’s throats – both metaphorically, and literally.

During one particularly saucy session, Steph and Jezza were so loud some of their housemates fled the bedroom to escape the sounds.

The couple went on to have a turbulent relationship outside the house.

Stephanie gave birth to their son Caben-Albi in January 2017.

Chloe Ferry and John Grimes

In 2017 Chloe Ferry got into trouble with Big Brother for her “unacceptable” behaviour towards Jedward singer John Grimes, after getting out of the shower and wiping her naked bum on him.

But she couldn’t resist another chance to get up close and personal to the Irish lad – giving him a sexy lap dance.

Chloe dressed in a sparkly orange bikini for the performance, which saw her straddle John and twerk in his face.

And he was so enthused by the Geordie Shore star’s gyrating that he ended up falling backwards on his chair.

Nicola McLean and Frankie Cocozza

A game of truth or dare during the ninth Celebrity Big Brother series in 2012 almost cost married glamour girl Nicola McLean her marriage.

After a boozy session, the ex-Page 3 girl got amorous in the hot tub with naked X Factor star Frankie Cocozza.

Having shared a smooch with the rebellious 19-year-old, fellow housemate Romeo Dunn had to drag the then 31-year-old mum off to bed before things got out of hand.

Nicola was mortified the next morning when housemates told her what she’d got up to and even threatened to quit the house.

She tearfully told Big Brother in the diary room: “My husband [footballer Tom Williams] means more to me than being on a programme.”

Nicola later claimed appearing on the 2012 series of CBB was “the worst decision of my life”.

Luisa Zissman and Jasmine Waltz

Big Brother has seen its share of girl-on-girl action over the years – but one of the most memorable scenes was between former Apprentice star Luisa Zissman and American model Jasmine Waltz in 2014.

After Louisa dared N-Dubz singer Dappy to “snog the duck” (a rubber duck) in the hot tub, he got his revenge by daring Luisa to snog Jasmine – with tongues.

Luisa duly obliged while Dappy rubbed his crotch in approval.

Megan McKenna and Scotty T

It wasn’t all about Stephanie and Jeremy in 2016 – Towie star Megan McKenna and Geordie Shore lad Scotty T also got close in the house.

After a brief period of ‘will they, won’t they’, the couple finally gave in to their feelings and shared a sexy snog.

A particularly steamy moment was shown on Celebrity Big Brother’s Bit on the Side, where Megan climbed into bed with Scotty in sexy black lingerie.

Clearly delighted, Scotty welcomed Megan with a cheeky bum squeeze.

Things turned sour after the pair left the house, with Scotty branding his former flame an “absolute f*****g nightmare”.

Lee Ryan and Jasmine Waltz

It may not be the most romantic setting – but when you’re living in a house with hundreds of cameras, the toilet feels like the most logical place to steal a cheeky kiss or two.

That’s where Blue singer Lee Ryan and model Jasmine Waltz spent a lot of time in 2014 – with the taps turned on to hide any noises (you know, like you would in school).

Unable to keep their hands off each other throughout the series, Jasmine later admitted: “In the toilet on the spaceship we kissed and made out and did stuff – but we turned on the taps so people wouldn’t hear us.

“We wanted privacy. We got very close. Let’s just say we did everything we wanted to do in there.”
