Justin Bieber might be celebrating the release of Purpose this week, but all is not well in his world. The attacks at Paris rock club Le Bataclan last Friday (Nov. 13), which left 129 dead and 352 wounded, affected the Biebs in a real way: He lost a friend in the tragedy.

On Monday, Justin decided to pay tribute to Universal Music Group executive Thomas Ayad, a product manager for Mercury Labels, by penning a emotional, heartfelt tribute. You can read it above.

This isn't the first time Bieber paid tribute to those lost in the attacks: During his performance at the Nickelodeon HALO Awards this weekend in New York City, Justin asked for a moment of silence.

Wishing you the best, Biebs.
