Country music's royal baby has arrived! Country music scion Holly Williams and her husband Chris Coleman are proud new parents to their first child, daughter Stella June Coleman, her rep confirms to Us Weekly.

Singer-songwriter Williams — the granddaughter of the legendary Hank Williams Sr., and daughter of Hank Jr. — welcomed their little girl in Nashville on Tuesday, Sept. 30, at 1:45 p.m. Baby Stella weighed in at 7 lbs., 12 oz., and measured 21 inches long, her rep tells Us.

Williams also took to Instagram to share her baby news with fans. "Hello world! Stella June Coleman arrived this afternoon," she gushed. "How does she have a perfect manicure?! Our hearts are mush and we are thanking God every single second for this healthy miracle of life."

As for the inspiration behind her daughter's name? Williams, 33, kept it in the family, bringing her great, great aunt Stella's name back, while June was the name of her grandmother.

Weeks before welcoming little Stella, her parents performed a duet at the Music City Food & Wine Festival in Nashville, on Sept. 21. She gushed to Us that her pregnancy was going well and she could not wait to become a mom.

Prepping for parenthood was made easier by Williams' celebrity pals. "Sheryl Crow has given me advice about touring on the road with little kids — you can’t be in a van anymore," Williams joked to Us at the Rolling Stone Country launch party in June. "And Gwyneth [Paltrow] has told me about making your own baby food and cooking and steaming food. And then you know Karen Fairchild [Little Big Town] is really good about balancing baby time and tour time. I have a good girl group."

This is the first grandchild for country strummer Hank Jr., who fathered Holly with his ex-wife, Becky White. Williams, in her pregnancy announcement this past May, told Us: "Mom and Dad are unbelievably excited." She added that they were "ready to spoil the little one!"
