Justin Bieber Mourns the Loss of a Friend in the Paris Attacks

It's been several days since the attacks in Paris shocked the world. Millions of people have been affected by this terrible tragedy and many are speaking out. Several celebrities including Harry Styles, Katy Perry and Nick Jonas have taken to Twitter to voice their compassion for the victims and all those affected.

Justin Bieber's tribute was a little more personal; a friend of his, Thomas Ayad (who is an executive at Universal Music Group), was killed in the attack. He was attending an Eagles of Death Metal Concert with other team members at Le Bataclan when gunmen opened fire on the audience.

Early Tuesday morning Bieber sent out a message dedicated to Ayad. The caption reads “RIP Thomas #PrayForParis.” He urged his fans to appreciate people while they are still a part of their lives, just as he wishes he appreciated Ayad more when he'd had the chance to.

We'll never be able to fully understand why people commit such horrific crimes—and we never know when or where they'll occur. So, like Bieber says, make sure your loved ones know how much they are appreciated, and hug your family and friends a little bit closer.
