After changing their name to Lady A for racial sensitivity reasons, the pop-country trio formerly known as Lady Antebellum then decided to sue a blues singer also named Lady A over their right to use the name. The lawsuit, filed in Tennessee court this week, claims that the band registered the Lady A trademark years ago and that Anita White, the 61-year-old Black woman who has performed under the name Lady A for decades, made an "exorbitant monetary demand" of $10 million in exchange for shared use of the name.
