Lily Aldridge, 30, took to Instagram to post a throwback photo of her wedding dress in honor of her fourth anniversary with Kings of Leon frontman, Caleb Followill.

The snapshot shows the supermodel, in a breathtaking white gown, and the singer, in a crisp grey suit, sharing an adorable kiss at their reception.

The photo may come as a surprise to some fans, because although Taylor Swift's bestie bares just about everything for her sultry Victoria's Secret and Sport Illustrated Swimsuit shoots, she rarely posts intimate pics.

The duo married in 2011 and welcomed daughter Dixie Pearl Followill a year later.
