Well we all know what Mariah wants but what about the rest of celebville? We asked some of 2012's biggest celebs - including James Arthur, Keith Lemon and Little Mix - what they were hoping to find underneath their Christmas trees this year.
Now, anyone know how to wrap 'a message from Justin Bieber'?
"For Christmas I want to see my family, have a bit of Christmas dinner with them and watch some rubbish TV. Only for a day or two and then get back to work. I'd like to have car, I drive but I don't have a car."
"I want some Louboutins. Everyone will be well jel."
"A jacket like what Ferris Bueller wore in the film 'Ferris Bueller’s Day Off', some Louboutin shoes, the 'Mouse Trap' and 'Guess Who?' board games and me new book, 'Being Keith'."
"Some sleep is at the top of my list! Nothing really, I just want barbeques and family and all of that. My sister is coming out to do the fireworks. She's creative director of the New Year's Eve fireworks. We're very proud of her. It will bring the new year in with a bang."
"For our Cancer Research initiative to raise as much money as possible."
"A record player and sound system for my house, an Art Deco cupboard to put my new TV in, some books that will change my life and inspire me and some new socks... I love putting on new socks so much."
"There's a few things, but I want to get the new iPad mini. I think that looks very cool. The iPad was too big for me but the mini I think I could get right into that. It's cute isn't it? And I want to play the piano on it like in the ad. Play chopsticks and really annoy everybody."
"If I was in a situation where I could I would love a dog. I know you shouldn't say that at Christmas. I'm so busy at the moment I couldn't. If I want something I'll go and get it. But probably just to see all my family and friends, I guess. I had a bulldog and I loved him but I don't see him anymore so maybe an English bulldog."
"A Kindle, as I would like to start reading more. A handheld vacuum cleaner as I’m a clean freak and a vegetable steamer as steamed vegetables are healthier."
Jesy Nelson (Little Mix)
"A number one album".
Leigh-Anne Pinnock (Little Mix)
"A long-awaited message from Justin Bieber would make December 25 extra special."
"The new 007 Omega watch and Halo 4 on Xbox."
Alex: "Time off, roller skates and a holiday." Karis: "More makeup, tickets to see Rihanna next year and a gift for my new flat." Courtney: "Another kitten, a holiday, and an iPad."
"I want some down time with my family. I've been neglecting them for ten years and I think it's about time I paid them a little bit of attention."
