Partnering with former Celebrity Big Brother housemate Darren Day to create the track, the 39-year-old TOWIE star is hoping for a number 1 festive hit.
Watch the video here:
In footage that Gemma shared with her 2m Instagram followers, the singing duo are seen rehearsing the famed Christmas track Baby It's Cold Outside.
Dressed in a glamorous full-length sequin gown, Gemma belts out some impressive notes, while Darren provides the male vocal interludes.
As one point, the TOWIE favourite forgets the words, and drops the F bomb, singing: "Honey, I've f*cked up the words."
Luckily, the GC handles the slip up like a pro and continues singing - we'd expect nothing less, tbh.
The charity single will raise vital funds for 'It's OK not to be OK', a mental health awareness campaign by Tony Wilsher.
Sharing the clip to Instagram, Gemma wrote: "SENTIMENT at this time of the year is very much needed ! The MAGIC of Christmas and everyone needs a MIRACLE right now !!!!
So myself and @darrendayofficial are making a CHARITY single for @iokn2bok20 for mental health and addiction! sending love and support to everyone who is struggling right now.
"you never know we could get this amazing Christmas fun loving filled heart warming song to NUMBER ONE #themagicofchristmas".
Making a jokey reference to her time spent on Big Brother with Darren, Gemma added: "I will have to throw in somewhere IM CLAUSTROPHOBIC DARREN !!!!!
"It's not perfect yet but practice makes perfect!!!! #imclaustrophobicdarren".
Let's be real: we always knew Gemma was Essex's answer to Mariah Carey.
Bring on the single! We can't wait for these two crooners to bring some festive cheer into the charts.
