Aunt B is not a big Lady A fan, and in fact loves to spread ugly rumors about Charles and bandmates Hillary Scott and Dave Haywood. "I've heard all kinds of stories: Hillary 'Skank' ... Dave hates babies. And that Charles, he's like a giraffe."
Watch below as Aunt B compares her own holiday album to Lady A's "On This Winter's Night," and tries to prove why she's the real "lady" of the group.
