Yep, the two Geordies are heading overseas to join eight other lucky (or should we say unlucky) singletons to star in MTV's most devious dating show.
Cue the drama...
Known for their on/off relationship on Geordie Shore, Charlotte and Gary recently struck up their romance once more in the latest series of the show.
After splitting with her former boyfriend Mitch Jenkins, Charlotte couldn't resist falling back into the arms of her former flame - not that Gaz seemed to mind too much.
But, despite their brief love affair, Charlotte soon called it a day and their romance was no more.
Now, both Gary and Charlotte are moving into the Ex On The Beach villa, not only with each other, but with a few surprise exes too.
And, for ladies man Gaz, he won't just have one ex joining him, but several.
Ooo, this is going to be good!
Ex On The Beach takes a group of singletons on an exotic holiday in the hope of finding love, only for the guys and girls to be joined by a few blasts from the past along the way. This time round, Gaz and Charlotte will be sharing the villa with eight other people including an Essex boy, a model, a footballer and a Dreamboy.
But, if the pair need any advice at all, they can always turn to their former Geordie Shore co-star Vicky Pattison.
Last series, Vicky jetted off in the hope of finding romance, only to find herself coming to blows with ex fiancé Ricci Guarnaccio.
Vicky and her ex hadn't seen each other since their bitter split, and on their reunion, not surprisingly, things got pretty heated.
In a final showdown, the outspoken Geordie revealed why things were so frosty between them, claiming Ricci had sold a story on her after their split.
With Charlotte and Gaz's relationship being just as fiery at times, we reckon series two of Ex On The Beach is in for plenty more fireworks...
We. Can't. Wait.
Ex On The Beach returns to screens on Tuesday 27 January at 10pm on MTV.
