Gary and Lillie dated for just over a year, before the pair confirmed they had split in November. Since then, she has found herself with a growing following and now Gary has claimed it's all because of him.
The reality star liked a telling tweet on Twitter recently that read: "@LillieGregg be thankful to @GazGShore no one knew your name before him!!"
At the time of their break up, Gaz and Lillie had assured fans they ended on good terms. However, it soon seemed like things weren't as amicable as first thought, when Gaz appeared to hit out at Lillie on Twitter.
After it was announced she had signed to a celebrity management agency as a 'Fashion Designer, Model and Social Media Star', Gary tweeted: "'Social media star' wow man this is getting embarrassing."
Gary then went on to date his co-star Charlotte Crosby and Geordie Shore fans recently saw him admit their relationship was one of the reasons he decided to end things with Lillie. During series twelve of the reality show, viewers watched Gaz struggle to balance his friendship with Charlotte and his relationship with Lillie, as he and his on/off flame grew closer again.
Since filming, he and Charlotte had been trying to work out if they had a future together. Their romance seems to be on hold at the minute, though, thanks to reports surrounding Gaz's behaviour on Ex On The Beach.
Charlotte has pretty much confirmed he'll be on the new series of the show and it's since been teased Lillie will be surprising him as his ex.
Ahead of Gary jetting off to filming in Thailand, Charlotte had claimed she wasn't worried about him coming face-to-face with Lillie because he "hates" her and thinks she is a "fame-hungry sl*t."
Lillie, however, hit back at Charlotte's claims she is fame-hungry. She said: "Maybe you should respect I fell in love with a boy that was in the media eye... I kept it quiet for 6 months... As I didn't want the world knowing about my relationship but I had no choice.
"Unfortunately we broke up and I am the one that has acted like a grown up by not tweeting / selling a story / or speaking publicly about our separation. The fact I haven't reacted to all the CHAZ remarks and nasty comments put my way is because I have some self respect and dignity and don't need to be nasty or lower myself to them / people."
She is now dating Ex On The Beach star Stephen Bear and he appeared to confirm Lillie's appearance on series five of the dating show, by teasing the new lineup on Snapchat recently.
MTV are still yet to confirm the official cast.
Following news of her new romance with Bear, Gaz told Reveal he wishes the couple well for the future.
He said: "I like Bear and get on with him. Lillie is a free agent and can see who she likes. I wish her and Bear well."
