Model Kaia Gerber, daughter of Cindy Crawford, took to her Instagram stories to share her own tribute to Mickelson, writing: "I remember that time we sat on the couch and spent the whole day coming up with our own secret language that we continued to speak every time we saw each other.

"I wish we could go back there. I wish we were still talking in sentences that probably annoyed everyone else but made us crack up every time.

"I wish I was still sitting on my bathroom floor FaceTiming you, because that was the only place I had wifi and I never wanted to miss a call from you. thank you for being the reason for so much laughter and happiness in the world. it won't be the same without you here. I love you Daniel."

"I don't want this to be real," she wrote in an accompanying caption. "Words can't even describe how I'm feeling right now. Last night I lost my best friend in the whole world. I feel like my hearts been ripped out of my chest.

"Daniel you were the kindest person I have ever met. You lit up every room with your contagious smile and never failed to make anyone happy. There wasn't one day that went by where you didn't go out of your way to make me feel special and loved. I wish I could call you right now and hear you tell me everything is going to be okay.

"I wish my plans to spend the rest of my life with you weren't stripped away from me like this. I wish I could tell you how much I love you and I wish I got the chance to say goodbye. I'm not sure how I'm going to get through this but I'm going to be strong for you because I know it's what you would have wanted.

"Everything I do now is for you. Now I have a guardian angel by my side for the rest of my life. I am going to make you so proud. I love you forever babe."
