Beginning with the super-skinny singer in the early 2000s to the burlesque form Christina showed in 2012 to finally the skinner diva-like avatar now - Aguilera, now 32, has really been working hard to get her body back in shape.

She received a lot of flak for her excess curves in 2012 which she brushed away saying that she was embracing her curves and liking her body. Weight-training with fitness pro Tee Sorge and plenty yoga has made so much difference to this now-svelte star. With Christina, it has to be exercise she enjoys and fitness becomes more of a mind-to-body thing then.

And yet since early this year she seems to have lost oodles of weight. Results had begun to show at the NBC's "The Voice" Season 4 in March. She wore an LBD with a cut-back in white and a flouncy skirt - paired with a studded belt. Pretty coral lips an simple lose hair made her look beach-kissed.

Everyone sat up when she came to the Time 100 Most Influential People In The World Gala where she performed and looked like a million bucks. She a keyhole-cut Victoria Beckham dress emphasizing her famous cleavage and paired it simply with Christian Louboutin shoes and Lorraine Schwartz jewels. Her beauty was fairly simple with blonde locks in a side-swept waves and classic red lips - absolutely no OTT.

Now the world is in a tizz with her absolutely svelte figure and toned legs. On July 27th, she arrived at the NBC Television Critics Association Summer Press Tour event in a tiny pink mini-dress which showed her toned body beautifully. Paired with nude Christian Louboutin heels and barely there makeup with pink lips, dramatic liner and soft, lose hair - Christina looked gorgeous! Looks like her swagger is back!
