Christina Aguilera was once known for stripping down and showing off her assets. But as she grew up, she went for a more old Hollywood glam look, all the while baring her ample cleavage and curves. On her February 2012 Marie Claire cover, Xtina covers up and she still stuns! That’s called natural beauty.

Wearing a white jacket with navy piping, which picks up the soft ocean shade of her baby blues, it’s a subdued, sweet version of the singer. Her platinum blond hair is teased in waves and blown back off her face, while her lips look extra kissable in a soft pink hue. She’s not vamping it up a la Marilyn Monroe with crimson lips and the verdict is in: We likey! Aguilera remains glammed out, just in softer tones.

The spread photos find Aguilera dressed in nautical hues and that shot of her in the navy bustier and blazer? In one word: heartstopping!

The cover tag hints about what’s going on inside the magazine and in Xtina’s mind. It reads: “I love my body. .. My boyfriend loooves my body.”

That’s all that matters, girl.

It’s 2012 and that means new year, new Xtina, new season of ‘The Voice‘ and new album on the horizon. She addresses her not-so-hot 2011 – save for ‘The Voice’ — which was marred by her divorce, a public drunkenness arrest, a flop album (‘Bionic’) and a flop film (‘Burlesque’), all of which were topped off by ardent criticism about her weight.

“That was a rough year,” Aguilera said about trying to make manufactured pop on ‘Bionic,’ that didn’t rely on her best trait, which is her gorgeous voice. “Between my divorce and the other things I went through, a lot happened. It’s hard for anyone to go through that in public. But when you’re a celebrity and under a microscope, it’s 58 million times harder. I grew an even thicker skin after that hard year.”

It’s served her well and she’s not letting anything, especially words, bring her down, to borrow a line from her most famous song ‘Beautiful.’ She continued, “I’ve been through my highs, I’ve been through my lows; I’ve been through the gamut of all things in this business. Being too thin. Being bigger. I’ve been criticized for being on both sides of the scale. It’s noise I block out automatically. I love my body. My boyfriend loooves my body. My son is healthy and happy, so that’s all that matters to me.”

Xtina has those priorities in line.

But that doesn’t mean she isn’t aware of how her body shape fluctuates. She said, “I have certain physical features that I favor over others. We all have our areas.” The singer insists she doesn’t weight herself, instead seeing how the clothes fit and feel, saying, “I happen to be very confident in my own skin. It takes time to get to that place, but it’s all about embracing yourself and your body.”
