The Game is celebrating a major milestone in his daughter’s life.

The rapper took to Instagram to wish his only daughter, California “Cali” Dream Taylor, a happy 15th birthday with an emotional message reflecting on her growth.

“I’ve always taught my children to dream BIG & manifest the things in life that you want for yourself & I’ll be there to help every step of the way,” he wrote alongside a touching throwback video and photos of of Cali throughout the years.

In the video, a 3-year-old Cali tells her dad, “When I am 15, imma be able to stand up and ride my bike.”

To which Game replies, “I believe in you.”

“This video means the world to me because the little girl in it is my entire life!!!” The Game continued in his post.

The rapper admitted that even back then, he couldn’t grasp how quickly time would fly.

“Well, here we are @calilynndreamtaylor….. your 15th birthday & I am writing this in tears because I love you with everything God has instilled in me,” he wrote.

Adding, “So much that when I think of you, the times we’ve shared, the memories we’ve made & just everything us… I can’t help but to just breakdown at the joy of it all.I think the saddest part for me is not being able to go back n relive those precious moments with the smaller you, all while appreciating the young woman you’ve become.”

Calling Cali his “only daughter & the PERFECT one for me”, the proud dad said, “Thank you for being my LIFE. My WORLD. My EVERYTHING.”

Game also showed some love to his three sons, writing, “I love your brothers wholeheartedly but do know that it is YOU that we are all here to love, protect & praise.”

He ended the tribute with a playful nod to their inside joke: “Happy 15th birthday California Dream, today we shall see if you can ‘stand up & ride your bike’ like you said you would. You are the light of my life. Love Daddy… oh wait, I forgot…. It’s just DAD now.”

The Game shares his son King Justice Taylor and daughter Cali Dream Taylor with his ex-fiancée Tiffney Cambridge. He also has a son, Harlem Taylor, with his former partner Aleska Jordan, and son Blaze Taylor with Shaniece Hairston.
