The Game celebrated a major milestone on April 25—his son King Justice Taylor’s 18th birthday.

Taking to Instagram, the rapper shared a touching tribute to his “middle child & my best friend.”

“1st off… lemme start this by saying I absolutely love you son. Like really really love you !!! You mean the world to me & ever since the day you were born I’ve thought you were just a very kool kid,” he began.

The Game, who shares Justice with his ex-fiancée Tiffney Cambridge, didn’t hold back when speaking about how much his son means to him.

“I can remember shedding tears when you were 3 years old simply because of the amount of joy you brought into my life at that age & how much fun we had,” he shared. “Those days were some of the best days/moments of my life.”

He also spoke about how fatherhood has shaped him, calling Justice’s birth his “second chance at perfecting fatherhood & I am forever grateful to God for blessing my life with you.”

As a father of four, The Game made it clear that being a dad remains his most important role.

“I’ve been in your life 18 years & haven’t missed a beat. Being a father to you, your sister & brothers is my greatest joy & just because it’s your 18th doesn’t mean that this is where that stops.”

He closed with a promise that his love and support will always be there: “I  will be here to love, teach, protect & guide you through life as long as there is air in my lungs & I will never not be available for you in this lifetime or the next.Thank you for the trust & love you’ve given me in return son, for it will never go unappreciated. I have so much more I want to say but I think somebody is cutting onions in the barbershop so I’m a chill.”

“Happy Birthday Justice… I LOVE YOU.”
