Gaz had been dating Lillie before she got together with Bear four months ago, and while he had seemed to give the pair's relationship his blessing, Lillie has now revealed Gaz wasn't so keen on who sh moved on with.
Opening up about her exes, Lillie claims that Gaz 'didn't want to believe' that she and Bear were genuinely together.
She told The Mirror: "Bear is an awkward subject for Gaz because I don't think he ever wanted to believe we were a real thing. We've not spoken about it too much."
Lillie and Bear got together after meeting on the fifth series of Ex On The Beach. She had been on the show to surprise Gary as his ex and the pair finally got the opportunity to talk over their split and gain some closure from it.
However, Lillie's arrival did mean that she then had to continue living with Gaz in the villa - and that can never be ideal, having to watch your ex move on with someone else in front of you.
A month after filming back in April, Lillie and Bear went public with their romance and they had seemed pretty serious about each other.
They confirmed they were a couple on Twitter and both Lillie and Bear had introduced each other to their families.
However, the pair have now split after Bear controversially dumped Lillie while appearing on CBB and publicly moved on with his housemate Chloe Khan.
Bear told his housemates he wanted to be single again and claimed he doesn't think Lillie is 'the one' for him anymore. He then pursued a house romance with Chloe and their steamy antics had fans divided.
Lillie, meanwhile, has said there is "no going back" for her and Bear. She feels he has "humiliated" her for the way he has behaved on CBB and has said she deserves "more than that."
Lillie wants answers from her ex-beau and has now confronted him inside the CBB house, prompting Bear to tear up in the Diary Room after seeing her again.
Following her drama with Bear, Lillie's best pal Kayleigh Morris claimed she is back in touch with Gary and the pair are now on "really good" terms. Lillie confirmed that she and Gaz are speaking again, but appeared to dismiss speculation a reunion with him is on the cards.
She added in her recent interview: "We have been speaking as friends."
