It's rare that we get to see every stage of a celebrity baby's life growing up, and we kind of can't believe that Penelope Disick turned five this weekend!
The adorable Penelope, the daughter of reality stars Kourtney Kardashian and Scott Disick, celebrated her birthday milestone in style - and her adoring family were on hand to help her.
The tot is said to have enjoyed a Disney's Moana-themed birthday party, sharing the celebrations with cousin North, who turned four last month.
The girls are both reported to have been gifted Pomeranian puppies on their big days - how cute!
Taking to Instagram to pay tribute to her daughter, mum-of-three Kourtney couldn't help but gush over her little one.
"I cannot believe my baby girl is five years old today!" she wrote. "Happy birthday, my sweet angel. I feel so blessed to be her mommy every morning that I wake up next to her."
The Kardashians are known for their love of elaborate parties and gifts, and Kourtney went on to share a Snapchat of the birthday girl opening her presents. We wouldn't mind owning a pair of those cute 'high heels', ourselves!
Penelope is quickly becoming known as quite the character within the famous family, and her birthday portrait - featuring her wearing lipstick and a tutu - is providing all of the proof!
The birthday tributes continued to pour in all day, with proud dad Scott simply sharing a photo of himself carrying his little girl. Proud grandmother Kris Jenner, however, took the opportunity to make a very public and sweet declaration of love for her second-eldest grandchild.
Sharing a photo-collage of the tot, the 'mom-ager' wrote on Instagram: "Happy birthday to our sweet princess, our little mermaid, Penelope! We love you so much, precious angel!"
In her birthday tribute, mum-of-two Kim thanked Penelope for being such a great friend and example to daughter North.
"Happy birthday, my sweet P!" she wrote. "Thank you for being the best friend to my North! I love you!"
We're sure Penelope - and North - had an awesome day!
