On a mission to get a Christmas tree in New York! 🎄#demkids #Christmas

It's the incredible shrinking Mimi!

Mariah Carey looked like a shadow of her former self while out Christmas tree shopping with her twins, and we guess those rumors about her getting gastric sleeve surgery were actually true!

The songstress has already shed a reported 25 pounds since the procedure, and she's looking hotter than ever!

"Mariah has always been proud of her curves, but this summer, as her Caesars Palace residency came to a close, and then she went on tour with Lionel Richie, she noticed it became harder to dance, and she was getting a lot more criticism online from body shamers," a source told Page Six about her decision to go under the knife.

"Mariah underwent the procedure about a month ago, and she is already seeing some good results, and she feels a lot better," the source added.

She has a lot to be excited about, other than her new physique. The Grammy winner also just won a reported $5-10 million settlement with ex-fiance James Packer. They never even got married, so why did she deserve so much money?! We're so confused!
