Jem, who has been holidaying in Thailand recently, came under fire after reports revealed she and Gaz had sex while filming for the fifth series of Ex On The Beach overseas.
Gary has chosen to stay quiet on the claims, with Jem insisting she has 'no comment' to make on the matter just yet - even if she did hint 'the truth will all come out in the end' on Twitter recently.
Many fans had been rooting for Gary and his Geordie Shore co-star Charlotte Crosby to make their relationship official, but she had warned things would be over for her and Gaz if he was to stray while filming for Ex On The Beach.
Reports had suggested a 'heartbroken' Charlotte quit Geordie Shore, after hearing the rumours about Gaz and Jem, although her rep has since denied this. That hasn't stopped fans of the 25-year-old from targeting Jem, though.
However, Jem has shrugged off the negative comments and sent out a defiant message to her haters earlier today. Sharing a selfie to Twitter, she added the tweet: "I see you haters. Here I am. Not giving a f**k."
She also dared to bare all on Snapchat, posing completely naked (while strategically covering her modesty) for her followers to see.
While Gary has since returned home from Thailand, Jem had stayed on to make the most of her trip. Yesterday, she shared a slew of racy snaps on Instagram as she soaked up the sunshine.
One photo showed Jem posing topless in the sea, while another showed the reality star baring her bum in a skimpy bikini. She told fans: "Feeling freeeeeeeee."
MTV are yet to confirm the official lineup for Ex On The Beach's fifth series, but Jem was rumoured for a return last month. She originally starred on the show during its third series. Jem arrived as Laura Alicia's ex and was reunited with her former flame Rogan O'Connor.
She joined the likes of Vicky Pattison, Jordan Davies, Megan McKenna, Kirk Norcross and Cami Li on the show.
Gaz, meanwhile, made his EOTB debut in series two. Charlotte has openly spoken of his return next series and recently admitted to Reveal she did get a telling off for letting it slip.
