Kings of Leon's Caleb Followill and his wife Lily Aldridge welcomed their first child, a baby girl named Dixie Pearl, into the world on Thursday morning. The 30-year-old frontman and 26-year-old Victoria's Secret model tied the knot in May of 2011 and clearly haven't wasted any time since. The little product of their "Sex On Fire" was born at Vanderbilt University's Medical Center in Nashville. 

After wrapping up the Australian leg of their international tour last November, the Southern rock outfit went on what was expected to be a six-month hiatus. The Followill brothers abruptly ended their U.S. tour—canceling several dates—in August of 2011 after an exhausted, overheated Caleb Followill left the stage during a performance in Dallas and never returned. 

Maybe he was taking time off to be with his wife? What do you think? Excited for KoL to get back into the studio?
