Lillie, who has never really opened up about her break up with Gary, has now shared her side of the story and admitted it was a "big shock" to hear the Geordie Shore star had wanted to end things.
She reveals Gary was given a choice between Geordie Shore or being in a relationship with her, and ultimately, he picked the show.
Speaking to Daily Star, Lillie explained: "No-one really knew what happened with me and Gary. It was a very intense relationship and very personal and private for me... We broke up because Gary was given a choice between Geordie Shore and me. He couldn't have carried on the show with a long-term girlfriend.
"The break up did come as a big shock, he broke up with me while at the airport and then jetted off to Australia... It was the first time I was properly in love. He was a lovely boyfriend... He chose his career over me and I get that."
Lillie and Gary announced their split in November last year, and at the time, both had assured fans they had parted amicably. Although, Lillie now claims she later found out Gary had been unfaithful while they were an item.
Reveal has contacted a rep for Gary for comment.
Viewers went on to watch Gary in series 12 of Geordie Shore, and he admitted he was struggling to maintain a relationship with Lillie while becoming closer to his co-star Charlotte Crosby again.
Fans later saw him leave the house and return announcing he was single.
When Geordie Shore returned for its Big Birthday Battle special, Gaz opened up to Charlotte and admitted that his relationship with her had been part of the reason why he ended things with Lillie.
They went on to pick up their on/off romance, and while there had been talk of the pair becoming an official couple, Charlotte and Gary fell out after she went public with her ectopic pregnancy. Charlotte then quit Geordie Shore, telling fans she wanted to put some distance between herself and Gaz.
