For Justin Bieber, the Paris attacks hit very close to home.
The pop star lost a colleague and friend who was killed during the attacks on Friday. Thomas Ayad, an international product manager at Universal Music Group, was killed at the Bataclan theater in Paris, along with 88 others, at the Eagles of Death Metal rock concert.
Bieber dedicated a post to Ayad on Twitter, and wrote, "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 continued. "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."
Universal Music Group Chairman Lucian Grainge wrote in a Saturday note to employees of Ayad's death that the loss was "an unspeakably appalling tragedy," reports the Los Angeles Times.
"I cannot even begin to express the depth of my sorrow," Grainge wrote. "On behalf of everyone here at UMG, we extend our most profound sympathies to his parents and all of his friends and family."
