Christina Aguilera closed out 2012 looking a little heavier than we're used to seeing her. She dropped out of sight for a bit but when she returned to the spotlight in March of 2013, she did so in va-va-va-voom fashion.

She got her hourglass curves back and she was a blonde bombshell of epic proportions.

We've gathered some of her best post-weight loss looks. Grab a towel to mop up the drool, boys.

Beautiful in a belted, black party dress. Her arms are tanned and toned and the heavy-on-the-hardware belt nips her at the waist, showing off her new shape.

Old Hollywood glam is Xina's forte and she didn't disappoint in this slimming, black Victoria Beckham gown, all the while dripping with bling.

A belted LBD really works on Xtina's curvy figure, so it's no shock that she reprised the silhouette. God, she's gorgeous.

This blush pink frock with a trumpet hem hugged every inch of her. Yes, it also showed off implants, but we love the platinum hue and softer makeup. When she ditches her black liner and red matte lips, she totally transforms her look. But the most intriguing thing is that BOTH looks -- ultra glam and extra soft -- work for her. #BeautifulInEverySingleWay.

Xtina paired skinny jeans with a flowy top, and it showed off her shape. We love the bedhead and vampy lips.

Another Marilyn Monroe-like moment for Xtina on the red carpet of the AMAs, showing skin in cutouts. What's that we hear? Oh, the sound of a siren!
