Congratulations are in order for country singer Holly Williams and her husband, musician Chris Coleman. The couple welcomed their second child, Lillie Mae Louise, on Tuesday (March 8).

Lillie Mae Louise joins her 17-month-old sister, Stella June. She weighed 6 lbs, 15 oz., and measured 20 inches long at birth.

"We are so incredibly excited to announce the birth of God's newest gift to us!" Williams tells Us Weekly. "Lillie Mae Louise Coleman has made our hearts flutter, and her big sister Stella June (18 months old) is beyond thrilled about the newest addition to our family..."

Williams and Coleman were recently in the process of moving from their old house into the home that used to belong to Williams' mother, she revealed on Instagram in early March. The house was undergoing renovations.

Williams is the granddaughter of Hank Williams and daughter of Hank Williams, Jr., and a notable Americana musician in her own right. She released her critically acclaimed most recent album, The Highway, in 2013. Coleman is a multi-instrumentalist who tours with Kings of Leon. The couple married in September of 2009, and welcomed their first child, Stella, in September of 2014.

Williams told Us she was well-prepared for balancing children and life on the road before Stella was born, having gotten ample advice from celebrity friends who were going through the same issues.

Sheryl Crow has given me advice about touring on the road with little kids — you can’t be in a van anymore,” she said. “And Gwyneth [Paltrow] has told me about making your own baby food and cooking and steaming food. And then you know [Little Big Town singer] Karen Fairchild is really good about balancing baby time and tour time. I have a good girl group.”
