Trisha walked out of the house late last night just after the latest eviction where Karthik got the boot.
Speaking on Bit On The Side, Rylan Clark-Neal broke the news: "Trisha has decided to leave the Big Brother house, make sure you tune into the main show tomorrow [Saturday] night for the fallout and all her reasons."
A spokesperson for Celebrity Big Brother later confirmed in a statement: "After 11 days in the Celebrity Big Brother Summer 2017 house, Trisha has decided to leave of her own accord and will not be returning."
This morning, Big Brother gathered the group to announce the news.
"This is Big Brother," boomed the voice, "Housemates, Trisha has left the Big Brother house and will not be returning."
Sam Thompson reacted: "Oh s**t, she actually went through with it! Girl got cajones!"
Jemma Lucy said: "I feel sorry for Karthik, not going to lie."
Sam added: "Let's get Karthik back!"
Shaun Williamson agreed: "Someone who appreciates it."
Sarah Harding added: "Karthik wanted to stay."
Trisha had been threatening to quit Celebrity Big Brother ahead of the live show if Sarah wasn't evicted.
Trisha, Sarah, Chad and Karthik had all faced the axe yesterday evening and it was Karthik who went.
On Thursday in the house Trisha complained after being put up for eviction again and took aim at Sarah, saying: “If I have to stay in this house with Sarah, I’m going to self evict."
The American vlogger had told Sam Thompson: "I’m not staying in the house with her."
