In scenes set to air later this evening, the 29-year-old vlogger was seen jiggling her breasts during the programme.
Wearing a strappy white vest top and appearing to go braless, the American internet sensation was seen grasping her ample assets and moving them up and down.
The star did the raunchy move while appearing to party with her fellow housemates ahead of tonight’s live eviction.
Along with Trisha, Chad Johnson, Karthik Nagesan and Sarah Harding are facing the boot after being nominated by their fellow housemates.
Trisha has had an eventful time in the Elstree compound after she was bodyshamed by fellow contestant Paul Danan after he made questionable remarks for why he was nominating her.
Speaking to Big Brother, the 39-year-old commented: “I don’t like the way that she sits around with her whole a***, legs… all naked like… just completely hangs out.”
Paul went on: “I don’t quite trust her… I’m a bit scared of her,” however it wasn’t long before he was branded “nasty” by those watching at home.
His comments sparked an online backlash from viewers, who raged at the ex-Hollyoaks actor on social media.
The former soap star has also had his share of controversy in the house after he clashed heavily with Girls Aloud star Sarah, 35, in what appeared to be a misunderstanding.
He ended up getting restrained by his fellow housemates after a blazing row with the pop star over something she had apparently said.
Paul later apologised for his behaviour after going into the Diary Room for a chat with Big Brother.
Celebrity Big Brother airs on Channel 5 tonight at 8.30pm.
