xtina-cover-230.jpgChristina Aguilera graces the February cover of Marie Claire, and she dishes on her fav fashion picks, being a mom and her weight gain. Of course, she took some time to strike a few sexy poses, and even though she's flaunting a fuller figure, she still looks fabulous!

On her body, the 31-year-old singer states, Ive been through my highs, Ive been through my lows; Ive been through the gamut of all things in this business. Being too thin. Being bigger. Ive been criticized for being on both sides of the scale. Its noise I block out automatically. I love my body. My boyfriend loooves my body ... I have certain physical features that I favor over others. We all have our areas. When I worked on Burlesque, I lost so much weight that I was too skinny. I don't weigh myself it's all about how I feel in my clothes. What looks good on one person might not look good on another body type. 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."

While Xtina has moved on with her life, no one can forget about the drama of 2010, which saw her going through a divorce, flubbing the lyrics to the national anthem at the Super Bowl and getting arrested for public intoxication. "That was a rough year," she admits, shaking her head. "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."
