We’re unsure if he was joking about the aunt thing, or if it was a mistake. Either way. the youngest Followill is excited to be an uncle.

The new parents married in May  2011 in Santa Barbara. Caleb’s cousin and fellow Kings of Leon rocker Matthew Followill was the first in the band to have a child, a son, back in April 2011.

Caleb has had his eye on fatherhood for some time. “I can’t wait to raise a family with her because she’s a great woman,” he said of his wife last year.
