Bear had been dating Lillie prior to his CBB debut, and despite promising her that he wanted to make things work between them, viewers later saw him end their romance onscreen and Bear moved on with his housemate Chloe.
He claimed he wanted to be single and said he no longer thinks Lillie is 'the one' for him anymore, before then pursuing an in-house romance with Chloe. Now Lillie has said she has been 'humiliated' by Bear on the show and she 'can't understand' why he has behaved in the way he has.
Lillie opened up about the breakdown of her relationship with Bear to OK! magazine and claimed she will not be forgiving Bear for locking lips with Chloe.
She said: "If he was in the house for a few months and I saw him gradually falling for someone that would be understandable, but I can't understand this. I can't imagine ever speaking to him again."
"There's no going back with Bear," Lillie insisted. "His behaviour is cruel."
Not only has Bear been seen kissing Chloe on camera, the pair were forced to deny speculation they'd had sex, after they were heard getting intimate together in the toilet. Bear insisted "nothing happened" and Chloe too recently denied the rumours, saying she wishes people could have seen what really happened.
Speaking about Bear and Chloe's steamy antics in the house, Lillie added: "The Bear I'm watching on the television is unrecognisable as my boyfriend. It never even entered my head that I couldn't trust him."
Despite not having made their relationship official before Bear's CBB appearance, Lillie insisted she and her Ex On The Beach co-star had been in love.
"Bear and I were in a full blown relationship for four months. We were in love, but we mutually decided to play it down as we'd both been in high profile relationships before," she explained.
"We'd even talked about getting engaged and moving in together, planning our future."
While Lillie didn't comment on Chloe in her recent interview, she did appear to hit out at the former X Factor star, after watching Chloe's interview on This Morning yesterday (15 August).
Chloe had claimed that she "didn't know" Bear had been in a relationship with Lillie until after she had kissed him for the first time. However, Lillie then questioned why Chloe would continue to pursue things with Bear once she had found out about his outside relationship.
Lille tweeted: "Just watched @itvthismorning - Bear is completely to blame. But to continue a physical relationship after you knew he had a girlfriend who he hadn't broke up with? And show no remorse?"
She then added: "#girlcode?"
So far Chloe has not responded to Lillie's tweets. She has, meanwhile, revealed her hopes that her romance with Bear will continue once he leaves the CBB house.
Speaking about their plans together, Chloe said: "He did ask me to wait for him and he said if he went [during Friday's eviction] he would wait for me. And he said we'd go away for a few days when he gets out and just talk."
