Ever the minimalist, Lily kept her beauty look simple with natural makeup and her hair in a slick low bun with a middle parting.
Sharing some words on Instagram, Lily wrote: "I've never wanted to be someone's someone more than I do yours, and now I get to be your wife. On September 4th, 2021 we officially became each other's forever. I love you beyond @charliemcdowell."
She added several other captions to subsequent images: "Never been happier," she wrote next to a picture of her and Charlie laughing together during their post-nuptial photoshoot.
In another post, she penned: "What started as a fairytale, is now my forever reality. I’ll never be able to properly describe how otherworldly this past weekend was, but magical is a pretty good place to start…"
The newlyweds first went public with their relationship back in August 2019 and haven't looked back.
In July last year Collins shared a picture with Charlie on his birthday, writing: "You’ve opened my eyes and deepened my heart. You constantly inspire me to dream big and go outside of my comfort zone. Every day is an adventure with you and I can’t wait to explore more of the world together (when we can). I love you so much..."
Barely two months later, the pair announced they were engaged. McDowell popped the question while the pair were on a road trip in New Mexico.
Announcing the news on Instagram, Charlie wrote: "In a time of uncertainty and darkness you have illuminated my life. I will forever cherish my adventure with you."
