The 21-year-old first entered the Borehamwood bungalow because she had a connection to Kieran after the pair met and had a one-night stand in Ibiza last year.
Isabelle’s entrance on the Channel 5 series, which has received concern over its future recently, has caused friction between the Ex On the Beach star and his ex-girlfriend Rebecca Jane ever since, while Isabelle is eager to become a fully-fledged housemate.
But that didn’t stop Isabelle from revealing the true nature of her tryst with Kieran to fellow housemate Chanelle McCleary, another Ex On The Beach transfer, who quizzed her on the encounter.
While Isabelle tried to play coy with the details of their night together as the pair chatted in the kitchen, she didn’t hold back from praising her lover.
Chanelle merely giggled in response to the sordid details as she sat in front of her.
Later on, the tanned blonde continued to make waves on the show when she was seen urinating in the hot tub before proceeding to continue the process in her bed.
Before entering, the contestant revealed why she thought she would make a good addition to the current lineup, saying that she’s “actually not a b****”.
The unemployed addition from Warrington also explained why she’d signed up in the first place.
“I want to have the best summer ever, I’m in between jobs at the moment so why the hell not?” She said.
Big Brother airs on Channel 5 at 10pm.
