Mark and Simon both made it all the way to this weekend's Strictly final and marked their achievements with a trip to Essex nightspot Faces.
Getting into the Christmas spirit, former TOWIE star Mark even donned a special Christmas jumper for the occasion, complete with a spangly picture of Rudolf on the front.
Now he's worn sequins, there's clearly no going back!
Posing for a snap with Blue singer Simon, Mark told his followers: "Me and @simonwebbe1 in Faces!! Strictly finalists!! 3 dance offs each!! We made it all the way!! Love this guy!!"
Mark finished in fourth place on Saturday night's Strictly Come Dancing, with Simon making it to the final three.
At the last post, however, he was beaten by Caroline Flack - who was crowned this year's winner.
Earlier today, Caroline - who recently split with her long-term boyfriend - admitted that Strictly Come Dancing had changed her life for the better.
