In addition to picking up two trophies at the 54th Annual Grammy Awards, the 29-year-old musician announced her pregnancy via Twitter. "Beyond elated to share that [husband] Nate [Yetton] and I are expecting our first child in late June!" she shared. "My baby bump and I will see you on the red carpet."
The singer-songwriter was congratulated via Twitter by Modern Family's Eric Stonestreet and Make It or Break It's Candace Cameron Bure, among others.
In the early stages of her pregnancy, Williams had "24-hour morning sickness for months," she tweeted. "There were days I thought it would never go away."
Williams and her bandmate John Paul White won the Best Folk Album and Best Country Duo/Group trophies. The duo also performed their hit "Barton Hollow" before introducing pal Taylor Swift, their collaborator on "Safe and Sound" from The Hunger Games soundtrack.
