The birthday girl posted several photos to Instagram, including one absolutely adorable snap that showered her mother with appreciation -- both in the caption and photo itself, which shows Tallulah cradling her mom.
"Thanks for holding me in your body for 9 months bb," Tallulah wrote.
"Love these beautiful humans so much," she wrote. "Couldn't ask for a better group of women to call my fam. Celebrating the birth of my baby girl @buuski I love you guys so much #famovereverything."
