Lead singer Caleb Followill and his wife, model Lily Aldridge, had a baby girl named Dixie Pearl a week ago in Nashville, Tenn. It was their first child. And last year, guitarist Matthew Followill and wife Johanna Bennett welcomed their first child, a son named Knox Cameron Patrick.

The Kings of Leon have been on hiatus, but Baylin, 28, has been busy promoting her album "Little Spark" and touring much of the spring.
