The Carolina Panthers player believes she helped him become a better father and man.
Cam Newton had a special message for his step-daughter, Shakira on her recent birthday.
Kia Proctor, his partner who he shares two children with, is her mother.
"Happy Birthday to the real girl who changed my life ever since we first met five years ago," said Cam. "You have challenged me in ways you will never know, because in retrospect you were my first child. This message isn't to brag or to even complain about my situation, but this is just real talk. Being labeled a stepdad is hard on the parent just as much as it is for the child to accept it. It is hard work for both parties and I respect any stepparent that takes full responsibility of a God sent child."

Adding, "I remember the first day you called me daddy and I was scared as hell. But when I thought about it, I was honored for you to think of me as not only a male figure in your life but also as a father figure you could learn from as well. Your mom and I are not married, but no one can tell you that I'm not your father and they damn sure can't tell me that you're not my daughter. I love you, or better yet, daddy loves you Kirry."
Cam and Kia recently welcomed a daughter, and have a one-year-old son, Chosen Newton. He's currently enjoying his off season time before training camp in the summer.
