Thirtyfour year old Christina Aguilera shares her new baby to the world on the cover of 'People' magazine. She shares, on being a working mom: “It’s definitely not easy juggling work and motherhood, as being a parent is a full-time job within itself. You just have to make it work for you. My life has so many different moving parts, but my kids are the center focal piece, and everything else shifts around them.” Which is not to say she has this parenting thing all figured out. “It’s hard to know you won’t have all the right answers at the right times. And ‘mom guilt’ is the worst thing ever,” Aguilera explains. “But you have to surrender and let go, knowing you’re doing your very best and no one loves them, or wants what’s best for them more than you.” Christina closes with "Max and Summer will always come first, they are the center of my universe.”
