Hoping to impress her new pals with her tanning expertise, Katie grabbed her rubber gloves and set to work giving Katie Hopkins, Cami Li and Michelle Visage a DIY holiday glow.
Although some onlookers didn't seem too impressed with the glamour model's handiwork.
Happy to tell the girls who's boss before she got started, Katie warned: "Be afraid, be very afraid."
Grabbing her first client of the night, Cami, she said: "Don't look, don't comment, just shut up, stand there and do as you're told."
Reassuring the girls they'll be bronzed to perfection, Katie told her housemates she did exactly the same to herself the night before. But not seeming convinced Cami asked: "Pricey are you trying to sabotage me?"
Kate then joked: "I'm going to make you look like the ugly sisters and I'm going to make sure I look beautiful... No do you really think I want you three on my f****** case?!"
After seeing the end result and the girl's tan-covered faces, the rest of the Celebrity Big Brother house were unsure how well Katie's tanning efforts would eventually turn out.
Alicia Douvall told Michelle: "That's not likeable. It looks like mud!... It's not a good look. Isn't it supposed to give you a sunkissed glow?"
We reckon it might be more mahogany by the looks of things!
The housemates' tanning session comes after they were told by Big Brother there will be no live eviction this Tuesday.
Following Alexander O'Neal's decision to leave the CBB house, the second eviction of the series has been cancelled even though housemates have already nominated.
Instead, viewers have been promised a live nominations twist.
Those nominated are Perez Hilton, Katie Hopkins, Alicia Douvall and Nadia Sawalha.
Katie P was immune from nominations this week as she only entered the house on Friday night, following Chloe Goodman's eviction.
Celebrity Big Brother airs nightly on Channel 5.
