Kris Jenner was among the first to publicly wish little P—the very first Kardashian granddaughter!—a happy birthday, writing in-part, "I can't believe you are 8... how time flies and how amazing it is to go through life with you and your sweet spirit and adorable smile."
"You are the best granddaughter, daughter, sister, cousin and friend... you are always so kind, thoughtful and loving," Kris continued. "I love you so so much my little angel! Have a magical day #HappyBirthdayPenelope #ProudGrandma."
"Happy Birthday Penelope!!!!! I love you so much sweet silly girl!" Kim wrote. "I really can't believe you are 8 years old! I couldn't have asked for a better bestie for North!"
The Keeping Up With the Kardashians star added that Penelope and North "together are so loving" and that they'll "always have each other!"
Penelope also got an endearing shout-out from her dad, who called her his "angel food cake pinop."
"The most thoughtful and special girl in the world who goes above and beyond making us all happy," Scott posted on his Instagram Story with a snapshot of his daughter sleeping peacefully. "I could never in a million years imagine life without you! [You're] my savior and heart."
"Happy birthday my sweet P!" Khloe captioned two photos of the pair. "You truly are a little angel! A gentle sweet wise soul! Koko loves you more than life itself!!! Where did the time go? ok omg crying!!
