Mark, 27, donned a bright red wig, fake boobs and a red dress adorned with ruffles and sequins for his new TV series, Party Wright Around The World.
In the first episode, due to air on ITV2 tomorrow, Mark flies to Miami to meet Alex and Miguel, who want him to throw the party of the century for their friend Joanna.
The former TOWIE star is already getting to grips with Miami's gay scene when Joanna tells him that she loves a man in drag.
So proving his dedication, Mark slaps on the make-up, false eyelashes and women's clothes - not to mention a glitzy necklace - before hosting the ultimate party for Joanna.
We have to say, Mark is a great sport for getting so involved - although we wonder what will his fiancée Michelle Keegan say when she sees the pictures?!
One thing is for sure - Kim Kardashian had better watch out, as there's a new bootylicious babe in town!
Party Wright Around The World, 9pm, ITV2, Wednesday 26 February.
