Congratulations are in order for Holly Williams and Chris Coleman.

The country singer, who turns 35 on Saturday, and her husband welcomed their second child – daughter Lillie Mae Louise Coleman – on Tuesday, March 8, she announced via Instagram.

“Our hearts have exploded for Lillie Mae Louise Coleman,” the proud mama captioned an image with the newborn.

Lillie Mae Louise weighed in at 6 lbs., 15 oz., and measured 20 inches long, Us Weekly reports. The baby girl joins 17-month-old big sister Stella June.

“We are SO incredibly excited to announce the birth of God’s newest gift to us!” Williams says in a statement. “Lillie Mae Louise Coleman has made our hearts flutter, and her big sister Stella June is beyond thrilled about the newest addition to our family.”

Williams – who is the granddaughter of Hank Williams and daughter of Hank Jr. – radiated the red carpet at the CMA Awards in Nashville, Tenn. in November.

Before the birth of her firstborn in 2014, the singer said she was feeling well prepared thanks to her A-list pals.

“Sheryl Crow has given me advice about touring on the road with little kids — you can’t be in a van anymore,” she shared. “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.”
