Bieber, 21, shared a touching tribute to Ayad on Monday with a special dedication on Twitter.

“Still thinking about Paris and my friend Thomas that we lost in the tragedy. He was a part of the team for years and I wish I would’ve had more time to thank him,” he wrote adding, “Make sure to appreciate people while you have them. Thanks Thomas for everything you did for me. You are appreciated and missed. Thoughts and prayers are with your family & friends #PrayForParis.”

UMG chairman and CEO Lucian Grainge confirmed Ayad was one of the 89 people killed in Friday’s attack at the Bataclan theater during the Eagles of Death Metal concert.
