The 28-year-old rocker is enaged to former J.Crew and Victoria's Secret model Lily Aldridge, 24, reports People. She appeared in the video for the band's hit song, "Use Somebody." The couple has been dating for over two years.
Caleb is just the latest member of the Followill clan to fall prey to the marriage bug. His brother and bandmate, Nathan, was married last Novermber to singer Jessie Baylin.
Nathan explained that at one point, he and other members of the band were a bit skeptical of long-term relationships.
"I mean, I don't think just anyone could handle being away from for 10 months out of the year, but you know, it kind of helped us not to attach ourselves to a certain place for too long because we knew we were going to up and leave. So early in our career it was perfect for guiltless sex with the groupies, but now that we all have relationships, it's a little tough," he said in an interview with AZCentral.
Kings of Leon's new album, "Come Around Sundown," is scheduled for release on October 18. Their last album, 2008's "Only By the Night," launched the band to superstardom, spawning three major hits: the aforementioned "Use Somebody," "Sex on Fire," and "Manhattan." The album has sold over six million copies worldwide.
The band is currently on tour in the U.S. and will head overseas next month.
