After spending months out of the spotlight, Christina Aguilera (and her sexy new figure) is working her way back into the public eye, just in time for the September 23 premiere of The Voice Season 5.

Over the past few years, the pop diva has had an on-going struggle with her fluctuating weight, often taking lots of flack from the press. But after taking a season off from the hit NBC competition show, Xtina is back and better than ever (and she wants you to know it).

The “Beautiful” singer posted a sexy photo on Twitter yesterday wearing a form-fitted black ensemble with a cutout midriff.

“What a great event yesterday for my fragrance, can’t wait to share it with you! #Unforgettable,” she tweeted.

Not only does her body look great these days but Christina seems to have gone back to basics when it comes to her hair and makeup. Honestly we’re pretty grateful, we could only take so much of the pink and purple hair tips.

These days the diva has returned to her platinum blonde roots and her looks appear more effortless and classic than gaudy and over-the-top.
