Celebrity Big Brother housemate Sam Thompson has been given a warning by Big Brother for his "invasive behaviour" on last night's show.
The Made In Chelsea star playfully flicked fellow housemate Jemma Lucy's nipple.
The reality star was trying on Trisha Paytas' revealing dresses and one of them left very little to the imagination.
As Jemma strutted around the bedroom wearing the see-through pink number she admitted she felt like a "fairy".
Sam then walked into the bedroom and was left stunned over the dress.
Me and Sam joke about with each other all the time.
He said: "What are you wearing? Oh look at those [expletive]."
The star then playfully flicked her nipple before Ex On The Beach star Jemma grabbed her breasts with her mouth wide open.
The tatted star was then called to the Diary Room by Big Brother.
Big Brother asked Jemma: "BB wanted to talk to you about Sam flicking your nipple."
But Jemma insisted that she was fine with what happened and wasn't offended by his actions.
She said: "It's just a joke. Me and Sam joke about with each other all the time. I don't take offence to it whatsoever."
Sam was then called to the Diary Room and given a warning.
After listening to Big Brother Sam, 25, said: "Yep. I get it."
Jemma has been a big character in the house since heading in last week.
The star was involved in an explosive row with Girls Aloud's Sarah Harding earlier in the week.
Jemma has made it very clear that she isn't a fan of Sarah and doesn't like the way she's been acting in the house.
Speaking with some of her fellow housemates Jemma revealed she thinks Sarah thinks she's "better than everyone else".
And all hail broke loose when Jemma hit out at Sarah, 35, Wednesday evening as she stuck up for friend Jordan Davies.
Reality star Jordan questioned Sarah over comments she had made earlier in the day about the different groups in the house.
But poor Jordan couldn't actually get a word in after Jemma and Sarah flew on the handle at each other.
Sitting in the smoking area Lucy tells Harding: “You keep thinking you’re different to everyone else.”
The pair then engaged in a full-on insult-filled row, with Harding telling Lucy she is “two-faced” adding “look at yourself mate, I don’t shag on TV for a living”.
Lucy hit back, calling the singer a “slag” and returned to the house to vent further.
Viewers were definitely at home with a bag of popcorn watching the drama unfold.
Sarah also ended up in another vicious spat with former Hollyoaks actor Paul Danan.
Despite hugging and making up just a few days ago it wasn't long before the two were at each other's throats yet again.
During last night's episode Sarah told housemates that former drug addict Paul was on medication.
Paul launched into a foul-mouthed rant at Sarah as another housemate tried to fend him off.
Ranting at the star Paul said: "Sarah, what are you saying?" Don't you ever say that [expletive]!"
Harding told him to "calm down", but he wasn't finished yet.
"No, I'm not going to [expletive] calm down!" he raged, telling Sarah that the "pill" in question had in fact been a paracetamol.
"I'm the one that's clean and sober – what the [expletive] are you doing?"
Paul later visited the Diary Room, where he apologised for his outburst.
Celebrity Big Brother continues tonight at 8:30pm on Channel 5.
