Taylor Swift wished her best friend Lily Aldridge a happy birthday with a thoughtful message on Instagram.

The 25-year-old "Wildest Dreams" singer sent the Victoria's Secret angel and swimsuit model well wishes on her 30th birthday on Sunday, according to Us Weekly.

Swift posted a photo collage of Aldridge and her 3-year-old daughter Dixie Pearl Followill on Instagram.

She captioned the post, "Happy birthday to a mommy who lets her little girl dress like a princess whenever she wants, and makes balancing a million things look effortless and fun. I'm so glad you invited me to a Kings of Leon concert six years ago. My life would be unrecognizable without you, @lilyaldridge."


The photo collage features four images: one of Swift holding Aldridge's daughter, who is looking into a telescope, and three of Aldridge holding her daughter. Dixie Pearl is Aldridge's daughter with Kings of Leon rocker Caleb Followill, whom the model married in 2011.

"Taylor is one of my best friends," Aldridge told Us Weekly back in November 2013. "We have so much fun together."

The close friends met six years ago at a Kings of Leon concert. They even walked hand-in-hand down the runway at the 2013 Victoria's Secret fashion show together.

Aldridge was also one of the many people featured in Swift's "Bad Blood" video. She is officially part of the singer's "squad," which also includes Karlie Kloss, Martha Hunt, Selena Gomez, Gigi Hadid, Hailee Steinfeld and Cara Delevingne.
