2012 was all about Christina's body -- in more ways than one. Not only was "Your Body" the lead single from her latest album, "Lotus," but the media won't let go of the fact that she had gained a few pounds. Still, Christina took the scrutiny in stride. "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," she told Marie Claire. "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 loves my body. My son is healthy and happy, so that's all that matters to me."
