In March, Turner commemorated the U.K. Mother's Day with a sweet post about her little girl on her Instagram Story. "Im so grateful to the two loves of my life for making me a mama. @JoeJonas and my beautiful baby girl," wrote Turner on her Instagram Story, adding, "Its my favourite job I've ever had."

Last year, in another sweet nod to her baby girl, the actress debuted a new addition to her tattoo collection in honor of their infant daughter.

The proud mom casually debuted the new ink baring her daughter's first initial in a selfie. A small "W" could be seen underneath her tattoo of the letter "J," which many fans believe she previously got as a homage to her husband.

Earlier this week, Jonas, 31, discussed his experience as a first-time dad, sharing that the extra time at home with his wife and little girl has been "amazing."

"It's been forced time at home — I'm always on the go, I'm always moving and traveling and touring. To be in one place for a solid amount of time and having my feet on the ground and be with my family, my immediate family, is time I don't think I'll get back," the musician said. "I'm so thankful and grateful."

As for what he's learned while parenting his "gorgeous" daughter, the singer discussed the importance of naps. "Naps are nice. All around," he shared.
