Remember Rebecca? The tattooed model and Gary reportedly dated for a year back in 2013 and now it seems like the pair have reconnected.
Gaz's latest Snapchat had everyone talking, as he was pictured with Rebecca sitting alongside him in his car. Cue his fans speculating why the duo were together again...
Are they dating again or are Gaz and Rebecca just old friends catching up?
Gaz is so far keeping quiet on the stir his latest snap has caused, but it seems his ex still has a bit of a hold over him. Rebecca also shared a few Snapchats of herself and the reality star, telling her followers Gary was "nervous" around her because he thinks she is "so hot."
She can be heard telling the camera that Gary is "nervous", while he refuses to look her way. Coming over all shy, he replies: "Don't..." Before changing the subject and asking where KFC is.
It's best not to jump to conclusions, though, as Rebecca has previously hit out at rumours concerning her love life. Back in March, she cryptically tweeted: "Humans P*SS me off. Can a girl not hang round with guys without people presuming something more."
So, what is the deal behind their reunion?
Whatever it was, fans weren't too happy to see Gaz enjoying the company of his former flame - after all the recent drama between himself and Charlotte Crosby.

However, some did approve of himself and Rebecca, with one fan commenting Gaz is a "lucky man" if they have rekindled things.
Others ruled out the possibility of a romance, pointing out that Rebecca has come out as a lesbian since dating Gary. She, meanwhile, hasn't addressed the speculation surrounding herself and her ex.
Gary and Rebecca's appearance together comes after Charlotte ruled out any hopes of herself and Gary giving their relationship a go.
Everyone had presumed the co-stars were dating, after they appeared to grow closer in recent month, but Charlotte has insisted she and Gary have been single the whole time. She suggested the pair were trying to decide if they do have a future together.
Gary had made it clear he wanted to make a go of things, but Charlotte revealed she still has trust issues when it comes to him and had her reservations as Gary had signed up to the new series of Ex On The Beach.
She had told Reveal she would have 100 percent committed to Gary, if he had stayed loyal during filming. However, while he was away in Thailand, reports revealed Gaz had bedded Jem Lucy, Charlotte Dawson and Olivia Walsh on the show.
Charlotte has since insisted she now wants to 'stay well away' from Gary, while he has hinted there are "two sides to every story."
Gary also slammed claims he had cheated on Charlotte Crosby - pointing out the pair were never an item. He responded to an article implying he had been unfaithful by tweeting: "You f**king kidding!! 'Boyfriend' since when were we boyfriend and girlfriend? Exactly we weren't!! So how can you say I cheated!?!?!?"
