Chloe had appeared on ITV's This Morning and had her say on her in-house romance with Bear. She claimed that she hadn't known about Lillie until after she locked lips with Bear and he brought up his relationship around the table in front of their housemates.
Lillie, however, has now questioned Chloe's decision to continue a romance with Bear following his revelation that he had been seeing someone on the outside.
She took to Twitter and directed a tweet at Chloe. It read: "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?"
Lille then added: "#girlcode?"
Chloe so far hasn't responded to Lillie.
Lillie's tweet comes after Chloe was grilled about her romance with Bear in the CBB house.
Host Ruth Langsford had asked Chloe if it had put her off Bear knowing that he was essentially "two-timing" Lillie and she replied: "I did think that. He said he'd made a decision he didn't want to be with her anymore and he obviously couldn't get out to tell her but he wanted it to be known he was moving on and didn't want to be with her."
She then revealed that the pair have planned to see each other on the outside and Bear has asked Chloe to "wait for him."
Chloe added: "We have plans. 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."
Chloe and Bear had divided fans with their steamy antics on the show, especially as Bear had been in a relationship. Initially he had kept quiet on his romance with Lillie, but later told housemates he doesn't think Lillie is "the one" anymore.
He claimed he wanted to be single and said he 'doesn't have time' for a girlfriend.
Lillie responded by telling fans there was "no going back" for her and Bear. She also revealed in an interview with Daily Star that she is "embarrassed" by Bear's behaviour on the show.
She said: "He craves attention. TV shows are pressure. There's a pressure on people not to be forgotten about. I'm embarrassed and can't go back on what's happened now. I'm worth more than that."
Meanwhile, Bear's Ex On The Beach co-star and Lillie's friend Kayleigh Morris has implied the pair's relationship was "more serious" than Bear had let on.
She claimed Bear had been planning on buying Lillie an engagement ring. Kayleigh said: "He has made it seem like they were not that serious on the show, but just a few days before he went in, he's telling her he loves her and talking about marriage."
Lillie and Bear met while filming for Ex On The Beach's fifth series back in April. They went public with their romance a month later.
