Britney Spears' sons have grown up in the blink of an eye. 

The pop icon's two sons, Sean Preston Federline, who is two days shy of 11, and Jayden James Federline, 10, celebrated their double-digit birthdays early with help from their famous mom. With just a year and two days between them, Spears celebrated the milestone by throwing a dual Pokémon-themed bash over the weekend complete with an assortment of adorable Pikachu treats. 

"Big bday for my boys! Double digits whoop whoop," Spears gushed on Instagram with a photo of her two sons smiling in front of their cakes. 

Britney spared no decoration—the songstress even had "Happy Birthday" spelled out in balloons hanging over their family pool. "Such a great day," she wrote on social media.

While she is the adult of the trio, motherhood has taught Spears a few things, too. 

"Becoming a mother and being with my boys has made me so much more accepting of myself," she told Marie Claire UK. "That has been a really big thing for me over these last few years."

Unlike their famous mom, Sean and Jayden have spent most of their young lives out of the spotlight, but that hasn't stopped Spears from publicly expressing her love for her two "masterpieces."

"You are my masterpieces. From the day I saw the most precious eyes, I believed in miracles to the core," she wrote in a post published on Time magazine's website on Mother's Day this year. "Such a gift God has given me, exploring in your beautiful worlds every day. I pray as a mother I teach you strength and passion to carry through the struggles in the world. Most battles will always be won on your knees. I pray you find your dreams."

Happy Birthday Sean and Jayden!
