Earlier this month, Charlotte released her very first autobiography and in it she dishes all on her most embarrassing moments as a teen, finding fame on Geordie Shore and, of course, her on/off romance with ladies man Gaz.
But not phased by what his former flame has to say about him, Gary told The Sun: "I'm not worried. I don't regret anything."
His relationship with Charlotte has had viewers hooked ever since they first got together in series one of the hit MTV reality show. Over the years, fans saw Charlotte fall desperately in love with her co-star, only for her to get her heart broken as Gary made it clear he didn't feel the same.
Spilling all about their relationship in the pages of her book, Char admits she was "stupidly in love" with Gaz, telling readers she only realises now her feelings for her co-star were a "one way street". She goes on to vent her frustration at Gary labelling her as his 'banker', stringing her along and pursuing other girls while he knew Charlotte still had feelings for him.
Despite leaving Charlotte upset on many occasions, Gary insisted he had always been honest with her.
"I've never lied to her," he added. The reality star then claimed he hasn't been stressing about the way Charlotte has portrayed him in Me Me Me, as he hasn't been anything but himself on Geordie Shore.
"I wouldn't ever go on telly and not be me," he said. "Sleeping with girls, getting p*ssed and having fun, that's who I am."
Thanks to his bed-hopping on Geordie Shore, Gary quickly found himself with a lothario rep. Now, though, he has curbed his womanising ways and is happily loved-up with girlfriend Lillie Lexie Gregg.
The pair first began dating last year and viewers were introduced to model Lillie for the first time during Geordie Shore's last series. Since then, Gary and Lillie's relationship has gone from strength to strength.
Although, ahead of filming for Geordie Shore's eleventh series, the couple were rocked by Charlotte's claims Gary had been two-timing Lillie with her when they first started dating.
While Gaz never commented on his co-star's allegations, Lillie hit back, insisting she trusts her beau "implicity".
She told her Twitter followers: "Gary and I are very happy and I trust him implicitly. We travel everywhere together and are virtually joined at the hip. I'm very happy and excited for our future... I'm taking no notice."
And proving so, Lillie looked nothing but loved-up during a romantic break with Gary in Santorini last week.
Declaring her love for Gary on the final night of their getaway, she said: "Our last night in Santorini... He said he wanted to take me here because I'd love it... I love it and I love you @gazgshore."
