The Daily Grind Video

Curvaceous Christina Aguilera has been sexy since her “Genie in a Bottle” days, but she’s come a long way from the stick-thin teen she once was.

The singer-turned-Voice judge has been spotted hitting the gym, reportedly teaming up with personal trainer Tee Sorge, and it is definitely paying off. Seriously…sign us up for whatever fitness plan she’s on. Almost overnight, Christina seems to have slimmed down!

In a photo she tweeted from the set of her latest music video, the barely-dressed songstress showed off some major curves, and a noticeably slimmer waist:

Fans of Christina’s sexy curves need not fret! They’re here to stay; in fact, she loves them…

“Actually, the challenge I’ve always had is being too thin, so I love that now I have a booty and obviously I love showing my cleavage,” she said. “Hey, if you can work it and you can own it, that confidence is going to shine through.”

We’re not complaining, girl.

Christina took a little break from judging The Voice to get back to her roots and make music of her own, but is set to return to the top-rated talent show shortly.

Hell yah, Xtina.
