Christina Aguilera, is that really you?
We couldn't believe our eyes when Xtina rose from the stage at the 2013 Billboard Music Awards today looking, well, like she did 10 years ago.
Debuting her svelte new figure in a cute little black dress, Xtina delivered a classic awards ceremony "wow" moment watch it unfold above!
The 32-year-old diva performed her hit with Pitbull, 'Feel This Moment', featuring a surprise appearance from the hit-maker who they sample, '80s A-Ha frontman Morten Harket.
A source close to Christina recently told People magazine that she's "exploring new methods of exercise" with various personal trainers.
Last September, Christina spoke of embracing her new curves.
"The challenge I've always had is being too thin," she told Lucky magazine. "So I love that now I have a booty and obviously I love showing my cleavage."
"If you can work it and you can own it, that confidence is going to shine through."
Xtina is set to return for the fifth season of The Voice in the US after letting Shakira warm her seat on season four.
Last week, Christina gave us a glimpse of her new bod on the set of her new music video. Check it out:
