We know it's pretty awesome to be a member of Taylor Swift's #GirlSquad and that is especially evident on birthdays. Swift sent her BFF Lily Aldridge a very sweet birthday Instagram collage complimenting her for being such a wonderful friend and mother.

On the collage, which featured pics of Aldridge and her daughter Dixie Pearl Followill (including one with Swift and the little girl, Swift wrote, "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."

Aldridge is married to Kings of Leon singer Caleb Followill. She was also one of the stars of Swift's "Bad Blood" video this summer.

Fellow celebrity friend Gigi Hadid also wished Aldridge a happy birthday on Instagram. Accompanying a black-and-white pic of her with a big look of excitement on her face next to Aldridge she wrote, "This is how @lilyaldridge makes everyone her feel, because she effortlesly exudes love, light, and support, without fail. Happy birthday my lils. You are such a special person and anyone that knows you is lucky for it. Lil sis loves you."
