Gemma, aka GC, teased her return last week by having a cheeky kiss with Pete Wicks under the mistletoe.
Gemma reunites with her BFF Bobby Norris for the festive hour-long special, as he, James 'Lockie' Lock and Pete visit her clothing boutique in Brentwood.
Getting all dressed up for the occasion, Gemma wears a bright red cardigan and a red-horned shaped headband as she treats the boys to some mince pies.
We must admit, this picture reminded us of the time when Gemma baked an apple pie for Mick Norcross, but ended up leaving it on his doorstep as he was nowhere to be seen!
Anyway, back to the Christmas special, it seems like Gemma makes use of having the lads in her shop, with Bobby putting up a mistletoe thanks to Lockie giving him a lift, and them helping her to decorate her shop.
It also looks like the fashion designer kits the boys out in some festive jumpers - well that's a necessity really, isn't it?!
Gemma quit TOWIE in August after starring on the ITVBe reality show for four years.
Fans can see her one-off return to TOWIE alongside Mario Falcone and Lauren Goodger, who filmed her return scenes with Chloe Sims and Danielle Armstrong.
The Only Way Is Essexmas airs on Wednesday 16 December at 10pm on ITVBe.
