Chatty Man host Alan has filmed a number of hilarious sketches for his end of the year party, Alan Carr's New Year Specstacular, which will air on Wednesday 31 December.
Getting into character, Alan donned a khaki shirt, red cargo pants and a blonde wig styled into pigtails to disguise himself as Gemma.
The sketch, 24 Hours in Celebrity Police Custody, mimics Gemma's time in the Australian jungle, during which she dramatically quit after just three days.
The sketch synopsis reads: "We are given exclusive insight into the torments of TOWIE's own Gemma Collins. After a long and harrowing 56 seconds in police custody, Gemma is at breaking point, having eaten her mattress and pillow from sheer starvation, she begins confessing to all manner of crimes, including her preference for Made in Chelsea."
After fashion designer Gemma quit I'm A Celeb, she revealed that she had suffered a "trauma", adding that counsellors had "advised her against" going into the jungle.
The bubbly reality star headed back to Essex - although much earlier than planned - and made her return on TOWIE during the Essexmas Christmas special last week.
We reckon Gemma loved Alan's sketch though, as she looked rather chuffed when she posed with Alan backstage this week.
After posing for a photo together, Gemma said: "Wow what a laugh I've had tonight, nice to catch up with my brother from another mother @chattyman such a laugh."
During the sketch, Alan also impersonates Cheryl Fernandez-Versini and Benefits Street star White Dee.
Alan Carr's New Year Specstacular airs on Wednesday 31 December at 9pm on Channel 4.
