Katherine Heigl's daughter Adalaide is growing up fast!
The actress shared a sweet post on Instagram in honor of the adorable little girl's fifth birthday on Tuesday.
"It is my sassy, fiery, break dancing, bug loving, whip smart, fiercely loyal, daddy's girls' birthday!" Heigl captioned a cute selfie of the pair. "HAPPY 5TH BIRTHDAY ADALAIDE MARIE HOPE KELLEY! I am so incredibly grateful for the light, the love, the laughter, the purpose, the joy and the grace you have brought to my life! Thank God the world has a girl like you to show us how it's done! #notthebabyanymore #littlethingsdontstaylittlelong."
Adalaide is one of Heigl and husband Josh Kelley's two adopted daughters. The Unforgettable actress also gave birth to the couple's first son, Joshua, in December.
The former Grey's Anatomy star recently opened up to ET's Cameron Mathison about the challenges of being a working mom.
"This is the first time that I have left him," she said about her first night away from baby Joshua. "He's just a little over three months now and I'm just here for one day and I thought, 'You know, it's irresponsible of me to disrupt his whole schedule for one day just because I have an issue.'"
The mom-of-three added that she had already Facetimed her baby boy from the airport and admitted she probably has a harder time with being away from him than he does.
"He's totally fine without me," she said.
