It's a match made in rock 'n' roll heaven—with a bunch of Angels standing in as witnesses.
And with these camera-ready attendees, we can't wait to see the rest of the wedding pics...
Among those celebrating were Caleb's bandmates and Adridge's fellow Victoria's Secret babes, including Alessandra Ambrosio. KOL drummer/older bro Nathan Followill was the best man.
On Wednesday, Caleb's younger bro/KOL bassist Jared dropped a hint that a wedding was in the offing on his Twitter page.
"Last night was a doozy. Thanks Silverlake. Now the drive up to.....where Caleb is getting married. My dad is riding with me. Could be fun," he tweeted.
The rocker, 29, and the supermodel, 25, first met at the 2007 Coachella Music Festival and have been dating ever since. News of their engagement broke last October.
The pair had been keeping their Big Day mostly under wraps, but the his fellow Followills offered up a preview at the premiere of Talihina Nights: The Story of the Kings of Leon, in which Lily appears throughout.
Jared told People that the actual ceremony was going to "may 25 people or so" but a lot of people will be at the party."
Congrats to the happy couple!
