The Kings Of Leon rocker and the stunning model are tying the knot in May and Lily has revealed the ceremony will contain all of the classic wedding features.
Speaking at the launch of Victoria's Secret's new Sexy Little Bride collection at the lingerie giant's Lexington Avenue store in New York City on Wednesday (20.04.11), she said: "My wedding is very traditional. I didn't think at first I wanted that. But now that it's getting closer, traditions are kind of nice."
The 25-year-old Victoria's Secret Angel has also picked out her wedding dress and the shoes she is going to wear on her big day.
She added to JustJared.com: "My dress is gorgeous and I'm so excited to wear it. I recently got my shoes and I was jumping up and down when I put them on."
Lily - who first met Caleb, 29, when Kings of Leon made their debut appearance at the Coachella music festival in 2007 - also recalled her first date with the 'Sex on Fire' singer, and has revealed they were both "nervous".
She said: "Our courtship was the most fun I've ever had. We always talk about how much fun we had. We loved every minute of it. Our first date was at the Nobu restaurant in London at the Metropolitan Hotel. At one point during the dinner, I asked him, 'Are you nervous?' He said, 'Yeah. And I was like, 'Me too.' "
