We don't know what motivated Christina Aguilera to slim back down to the bod she had back in the early 2000s, but she looks better than ever!

Xtina taped the Thanksgiving episode for The Tonight Show with Jay Leno on Wednesday in Burbank, and it looks like she's performing “Candyman” based on her costumes.

The singer appeared on Leno back in September, and that was the first time we got a peek at her dramatic weight loss. Xtina told Jay, "At this point in my life, I'm 32, and I feel sexier than ever just because you know what you want. It was all about appreciating the woman that I've become and effortless-sexy. Not trying too hard."
