Congratulations to Lady A's Hillary Scott and husband Chris Tyrrell, who will soon be welcoming a fourth daughter to the family! In an Instagram post alongside pics of their three kids sporting "Big Sister" bracelets, Scott wrote, "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. I’m dusting off that Maternity bin from the storage room ONE more time." Scott and Tyrrell just celebrated their 13th anniversary last month and share daughters Eisele Tyrrell, and twins Emory Tyrrell and Betsy Tyrrell.
