Hillary Dawn Scott-Tyrrell is an American singer and songwriter who rose to fame as the co-lead vocalist of the country music group Lady A. She is signed to Big Machine Records.

Lady A, known until 2020 as Lady Antebellum, is an American country music group formed in Nashville, Tennessee, in 2006. The group is composed of Hillary Scott, Charles Kelley, and Dave Haywood. Scott is the daughter of country music singer Linda Davis, and Kelley is the brother of pop singer Josh Kelley. The band abbreviated the name to "Lady A" in June 2020 during the George Floyd protests in an attempt to blunt the name's associations with slavery and the Antebellum South, inadvertently causing a dispute with Black blues and gospel singer Anita White, who had been using the name Lady A for more than 20 years.
