She is speaking from firsthand experience, after living with and starring alongside bear on Ex On The Beach's fifth series. Jess told us that she thinks Bear has two sides to him, but his love of winding people up can get the better of him, as he 'doesn't know when to stop.'
So far, CBB viewers have seen Bear cause uproar in the house thanks to his pranks. Remember when he wasted all the coffee to make a cocktail? Or how about that time he broke an entire box of eggs by deliberately tripping himself up, after telling the house he would make them all pancakes?
HIs housemates are starting to doubt when he is actually being genuine with him, and used to his constant joking, Jess told us: "That's just how he is always going to be and probably how he got in [the CBB house]."
Bear has seen himself fall out of favour with fans on Twitter several times, thanks to his wind up behaviour, but Jess has insisted he can be a "really, lovely guy."
She explained: "He's just being Bear - the ultimate wind up. There's some sides to Bear where he is such a lovely person and you can sit and have a chat with him, and there's another side where he just wants to wind people up and doesn't know when to stop...
"I certainly had that problem with him. If you just take him with a pinch of salt, he can be a really funny, lovely guy."
Bear's antics had him eternally nominated by his housemates, after they have grown tired of his wind up ways already. EastEnders star Ricky Norwood even claimed he could no longer be in the house with Bear there and told Big Brother: "Get him out of the house! I am fuming with him! He's an ugly human being, he's been trying to provoke provoke provoke."
The Ex On The Beach star has also been causing a stir due to his in-house romance with Chloe Khan. Prior to entering the house, Bear had been dating Lillie Lexie Gregg.
They initially met while filming for MTV's Ex On The Beach, and went public with their romance a month later.
Shortly after Bear's CBB debut, Lillie revealed she and him were yet to make their relationship official, but Bear had told her he wanted things to work out for them.
However, viewers have since seen Bear declare Lillie is 'not the one' for him anymore and he's claimed he is now single.
Bear then publicly moved on with Chloe and they have been seen kissing on the show on multiple occasions. The couple were recently forced to deny they'd had sex, after they were heard getting intimate in the toilet.
Bear told Lewis "nothing happened" between himself and Chloe, but the pair have indulged in steamy scenes since.
Lillie, meanwhile, has told fans there is now "no going back" for her and Bear, after admitting she was heartbroken.
