Christina Aguilera February 2012 Marie Claire

Christina Aguilera is the the cover girl for the February issue of Marie Claire Magazine, which hits newsstands Tuesday, January 17th.  Christina opens up about her rough year, her body, being a single mother and even Kelly Osbourne calling her fat.

Check out some highlights below:

On 2011: “That was a rough year. 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.”

On her body: “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.”

On single motherhood: “It’s hard not having the consistency of a partnership on a daily basis. It’s a struggle. But I can’t single out my ex-husband [as the problem] because he’s a devoted father and great with my son. We always make sure that we put Max first. I have help from family and good people around me in support of my career. I couldn’t do what I do without a strong team behind me.”
