Emily Atack, 28, was seen changing her clothes in the ITV show with the help of co-star John Barrowman.
The Doctor Who actor held a blanket around her body to shield her modesty from the rest of the camp and the public.
But John, 51, got a peek of her breasts as she whipped off her clothes in the jungle.
He said to her: “They can’t see any side boob, stand this way, oh now I can see them! It doesn’t matter as long as you don’t care.”
Emily couldn’t stop laughing as she jiggled around to attempt to keep her modesty in tact.
“They are so funny boobs, they are just wobbly bits,” she declared.
John appeared intrigued as he watched on and told her: “Your right one is bigger than your left one.”
The blonde beauty giggled: “Yeah, there is always a bigger one.”
Emily has become one of the favourites in the camp to win the show with her hilarious quips.
Earlier this week, the Inbetweeners actress, who played Charlotte Hinchcliffe, asked Harry Redknapp, 71, whether is son Jamie, 45, was single.
Emily joked to the football manager she would make a great daughter-in-law and mimed to the camera for Jamie to call her.
“Ooh imagine, Emily Redknapp, I would make a really good daughter in law,” she said.
“You would be fantastic there is no doubt about that Emily,” Harry complimented.
Now Jamie has responded to Emily’s gesture and admitted she’s “so sweet”.
The Sky Sports pundit said of the star: “She’s so sweet in the programme.”
He continued to The Sun: ”It was such a nice conversation and I thought ‘all right dad, where are you going with this one?’
“It was funny the way she handled it afterwards, it did make me laugh. He’s like Tinder in there, dad is isn’t he?”
Harry is the current favourite to be crowned King of the Jungle when the final airs on Sunday.
I’m A Celebrity… Get Me Out Of Here! airs on ITV at 9pm.
