Alex penned a heartfelt tribute on Instagram that reads as follows:
"My heart hurts so much right now. I still can't wrap my head around this. How can it be? I learned so much from Kobe Bryant. He was naturally gifted, but had a passion for basketball like no one else I've ever seen. His work ethic was impeccable and his stress on mastering the fundamentals is what elevated him to the player he was. I've never met anyone more focussed with a myopic approach. He didn't pursue approval, affirmation or adulation. He pursued excellence and process. He followed my career and would often call to help with my health, daily routine ... and would even chime in about hitting techniques. He was a role model to me, and millions around the world.
We met as teenagers. We followed similar paths. We went from high school to the pros and our baby girls grew up together. People don't know this, but he was my secret coach. He pushed me and motivated me, especially toward the end of my career when I needed him most. He was always there. Even after our playing days, he was there for me. He attended @Jlo's last show in Vegas. He appeared on TheCorp podcast.
I last saw him a few months ago. I will remember what he told me about how much he loved Vanessa and his girls, and that he continued to say no to 99 percent of offers, choosing instead to spend as much time with his family as possible.
I will remember his greatness. I will remember his guidance. I will remember his friendship. I will remember that he made me a better person.
His 13-year-old daughter Gianna was following in her Dad's footsteps. She was kind, smart, caring and going to be a star.
Rest in peace, Kobe. Rest in peace, GiGi. My heart and prayers go out to the Bryant family and the passengers' families."
