Just like Christmas comes but once a year, so does the brilliant annual heat Stars Dress Up.
Every year, we convince the greatest celebs in all of celebville to leave their diva demands at the door and have a shedload of fun with heat - we get them to dress up as other celebrities.
See Alan Carr do Lauren Goodger and Kim K! Keith Lemon's dressed up as Taylor Swift! It's all a big fat load of lols. Here's some of the best dress ups from the past few years, our Christmas gift to you.
