Just when you think you’ve got a handle on Christina Aguilera’s style, she switches things up — and that’s what we love about The Voice coach. She’s certainly toned down her style this season, as she was reportedly asked to do, and has gone with some very subdued colors, less makeup, and even a few demure styles. In fact, when she took the stage to sing her hit song “Say Something” with A Great Big World at the 2013 AMAs, she wore a simple, floor-length black gown with minimal jewelry and an uncomplicated up-’do.  

Last night, however, she and celebu-stylist Simone Harouche decided to go for a pop of color with Xtina’s fave hue — blue. The figure-hugging dress showed fans that, while she has definitely lost weight, she certainly hasn’t lose those famous curves. Don’tcha just love that about the pop diva?

We’re also a huge fan of her hair this season. As an inside source reportedly told In Touch before the season began, "She thinks she looks great and isn't hiding behind 10 lbs of hair extensions." Christina’s hair stylist, David Babali, calls her his “modern day Marilyn Monroe,” and last night’s hair was definitely a nod to the iconic actress. Let’s not forget Xtina’s signature final touches bright red nails and bright red lipstick.

We thought the whole look was pretty fabulous. How about you? Sound off in the comments!
