“My heart is beyond broken.💔😭 twitch was a best friend and a mentor not just to me but to SO many. I’ll never forget our time getting to work together on SYTYCD, he became such a light in my life. Someone I’ve looked up to since I was born turned one of my best friends,” JoJo shared on Instagram. “Twitch always had the best advice. We had SO many laughs, smiles, and even cries together. I know you’re in a better place now but man we are all gonna miss the hell outta you. Sending my most love and prayers to His beautiful wife and 3 perfect kids. ❤️ thank you for sharing your gift with the world. I’m “so esssicted” to see you again one day (A inside joke between us that I will never let go of). Forever the worlds dance dad. Love you brother.🙏🏼 RIP the legendary Stephen Twitch Boss❤️”

Leah wrote, “I am heartbroken by the news of the passing of tWitch. Although we had met many times at the Ellen Show, I got to know him better this summer when I joined the judge’s table on ‘So You Think You Can Dance.’” See her full post below.
