The 35-year-old singer told Women's Health that despite their long engagement, the couple are still in the beginning stages of talking about their wedding. "We discuss it when we're snuggling in bed," she said. "But it's a casual conversation."
Obviously, Aguilera is in a good place in her life -- but explains that balancing her needs with being a mother of two can be challenging. "Mothers are constantly expected to be the nurturers, the givers, the providers of a comfortable home," she explained. "We're expected to be pregnant, have the kids, breastfeed once we have the babies. And we're expected to look amazing after baby, right? Keep our husbands and boyfriends interested -- because we're supposed to get back to sexy and keep things exciting in the bedroom. There's such a long list. Having children is the ultimate joy, and I love my kids, but women have to find time to nurture themselves."

The Voice coach also called women out on being too hard on themselves. "If you're not feeling confident on a certain day, you have to let that go, and own, 'Yeah, I'm not feeling confident today' and you move on and try to enjoy the best you can," she said. "I'm not into deprivation; I'm not into suffering into getting a great body or the body that you want. I'm into enjoying life, being conscious and aware, but also breathing into yourself and owning what you got."
