Grammy winner, Voice coach, platinum-selling superstar — there are plenty of ways to describe Christina Aguilera, but to her kids, she's just mom. Christina has two little ones — Max and Summer — whom she adores and loves to spend time with when she's not out touring and selling millions of records. She shares Max with her ex husband, Jordan Bratman, and Summer with her current fiancé, Matthew Rutler. Christina and Jordan, who divorced in 2011, still amicably coparent Max. Christina even shared a photo of them on Max's 12th birthday, writing, "We make blended families work. It's a beautiful thing." Ahead, check out some of Christina's cutest pictures with her kids and get to know them better.
