Kings of Leon's Nathan Followill and wife Jessie Baylin expecting baby

There's a bit of a baby boom going on for members of the band Kings of Leon and for anyone claiming the last name "Followill." Drummer Nathan Followill and wife Jessie Baylin will welcome their first baby in December. The news comes just days after Caleb Followill and Lily Aldridge announced the birth of their daughter, Dixie Pearl.

"They are two of the most excited people I know," the band's rep tells Us Weekly.

Nathan, 33, and Baylin, a 28-year-old singer, met at the 2006 Bonnaroo music festival and married in Tennessee in 2009 with celebrity guests including Scarlett Johansson on hand. Guitarist Matthew Followill and wife Johanna Bennnett welcomed a son, Knox, in April 2011.
