Bear's now ex girlfriend Lillie Lexie Gregg has been branded 'FAKE' following her appearance on Celebrity Big Brother 2016.
Lillie joined CBB in Thursday night's show as part of a task to confront him over his antics with Chloe Khan in the house.
She said: "You asked me to be there when you got home, I was supporting you 100%. The embarrassment and humiliation I’ve had…this is all one big game to you, it is a joke at my expense.”
Bear, who had got together with Lillie after filming Ex On The Beach earlier this year, later told BB in the Diary Room: "I can’t be with her; it’s not fair on her. I was adamant I wasn’t going to get with no one.
"Everything happens for a reason…she’s had a lucky escape from me. It took me 26 years to find someone I care about…”
However Bear's older brother Danny Bear has now hit out at Lillie, accusing her of "fake" tears and being "incredibly fame hungry."
He told The Sun newspaper this week: “Stephen tried to end their very short relationship after we all saw through her, but once his contract for the show came through she started pulling at his heart strings.
“He might be an entertainer, but he’s also an incredibly caring, loving boy with a massive heart and fell for it and I really hope that he’s learnt a very valuable lesson from all of this.”
Speaking about Lillie's speech to Bear on Thursday night's highlights, Danny added: “The tears were fake and admittedly it was a very good performance which fortunately didn't fool everyone.
“Remember he met her on another reality show, she knows what she’s doing."
Tweeting after her appearance on the show, Lillie wrote online last night: "Hardest decision to go in the house...It was for closure & that's what I got. Thankyou again for all of the kind messages it's appreciated."
Celebrity Big Brother continues nightly on Channel 5.
