Earlier this month, Gary revealed he was single again, following his split with girlfriend of one year Lillie. Shortly after their break up, Gaz has been spotted kissing his former flame and co-star Charlotte on several occasions.
Ahead of the pair locking lips, reports had revealed Gary and Lillie's split wasn't as amicable as they had made out and claimed Charlotte had been involved. Rumours then surfaced that Lillie is set to appear on Celebrity Big Brother in January and is expected to dish the dirt on her ex-beau. And judging by Charlotte's latest tweet, it won't sit well with her if Lillie does enter the house...
Taking to Twitter, Charlotte appeared to hit out at Gaz's ex. Although she didn't tag Lillie directly, fans were quick to comment that it was the fashion designer Charlotte was talking about.
She tweeted: "If there is one thing I can gladly say about my ex boyfriend is that he wasn't a FAME HUNGRY twat! Unlike some ppls ex's! #Cringe #WhoAreYou."
Reading her post, one fan commented: "Defo Lillie cos shes going into big brother." While another said: "Can't you guys guess it's about gaz's ex clearly!!"
Adding fuel to the fire, Lillie's agent responded to Charlotte's tweet, hitting back: "When the shade gets thrown, like a bucket of ice... #glasshouses."
Lillie, meanwhile, has not yet mentioned Charlotte's comments on social media.
Charlotte's dig at Lillie comes after she and Gaz have appeared to rekindle their romance.
Gary had been dating Lillie, but claimed it was too difficult for him to continue their relationship while still appearing on Geordie Shore. He described their time together as "amazing", before wishing her the best for the future.
Lillie too reiterated there was no animosity behind the split. She had said: "We had the most incredible year and relationship! There is nothing and never will be anything bad between us."
Since then, Gary sent Geordie Shore fans into a frenzy after publicly flirting with Charlotte on Twitter. Holly Hagan then caught Gary and Charlotte kissing on Snapchat during a night out, and many were quick to share their hopes for a reunion between the pair.
Charlotte and Gary have since locked lips again, after Char confirmed her romance with Love Island star Max Morley was over. She had been dating him when she first kissed Gaz, but later called things off, after he publicly called her "mug" to the press.
Max had said: "Gary clicks his fingers and Charlotte comes running back, she's a mug for going along with it."
Charlotte told fans she had felt guilty about her smooch with Gaz, but later told Max she was glad she kissed her ex, after hearing what he had said about her.
"I've apologised so many times and heard this I don't ever want to speak to you again," she said. "I'm actually glad I've done it. You're overreacting."
