The couple welcomed their baby boy in March 2020.
Morris recently spoke to PEOPLE about her journey as a mother and how she's learned to love herself in her own skin. The Grammy winner explained that it wasn't easy at first to feel like herself after her body was "borrowed for nine plus months, plus postpartum."
"I feel like it really took me a second to realize, 'Hey, I don't need to just snap back to how I looked before to feel sexy or powerful or myself even,' " she shared.
However, the artist said she feels the "most comfortable now, at this age, a year after having my kid, and just knowing that I raised another human."
"I was the house, and I feel like that's given me so much confidence that I didn't have before when I was a size two," she revealed. "So I definitely feel like being a mom has made me feel really powerful in my own body because look what we're capable of."
