Lady A’s Hillary Scott Is Pregnant With Baby No. 4

Lady A is going to need to make more room on the tour bus!

Six-time Grammy Award winner Hillary Scott and her husband, Chris Tyrrell, are expecting their fourth little one. “Chris, Eisele, Emory, Betsy, and I are overjoyed to report that this summer our family will be made complete with the most precious little SISTER joining the family,” the couple announced on Instagram with a photo of their three little girls with big sister bracelets.

“I’m dusting off that Maternity bin from the storage room ONE more time,” she joked, sharing a photo of her box of essentials tucked away. “Four daughters. We are thankful that God has entrusted us with a household of little ladies, and I couldn’t be happier that my husband continues his streak as the absolute BEST girl dad, in my opinion!”

In the comments, friends, fans and other music industry powerhouse sent their congratulations and advice for handling a growing crew of four little ones. “Four is the craziest, most exhausting and logistically debilitating, and AMAZING most WONDERFUL life ever! Sending so much love,” wrote Hank Williams Jr.'s daughter, Holly Williams. “4s the lucky number. Can’t wait to meet this little nugget,” added bandmate and co-lead vocalist Charles Kelley.

Scott and Tyrrell are already parents to daughters Eisele Kaye, 11, and twins Emory JoAnn and Betsy Mack, 7. The two met in college and reconnected when both Lady A and Love and Theft, the band Tyrell played drums in, served as the opeing act on Tim McGraw’s 2010 tour. The two tied the knot in January 2012.
