Reactions to fatal shooting of singer Christina Grimmie, onetime contestant on NBC's "The Voice," who was shot Friday after a concert in Orlando, Florida:

"I'm stunned and disgusted and heartbroken that we lost that sweet little girl." — Blake Shelton (recording star and judge on "The Voice") on Twitter.

"I'm sad, shocked and confused. ... This just isn't fair." Adam Levine (recording star and Grimmie's coach on "The Voice") on Instagram.

"She was special. She walked in the room and she had an infectious laugh, she was determined, she was confident, but she was so incredibly sweet. You would never forget meeting her. I'm shocked she didn't actually win season six. Her star was shining so bright, which certainly makes this that much harder." — Carson Daly (host of "The Voice") on NBC's "Today" show.

"Christina was such a kind, generous person, and so talented. What a light has been taken from the world." — John Green (author of "The Fault in Our Stars") on Twitter.

"I'm sick about TheRealGrimmie. Praying for her family. Now I'm scared to do meet and greets." — RaeLynn (singer and former contestant on "The Voice") on Twitter.

"Senselessly tragic but now a heaven's angel." — Robin Leach (TV personality) on Twitter.

"Devastating tragedy." — Adam Lambert (singer-songwriter) on Twitter.

"Very tough to read things like this and sending lots of power and love to her family & friends." — Theo Rossi (cast member of "Sons of Anarchy") on Twitter.

"May her beautiful soul rest in peace." — Kristen Merlin (singer and former contestant on "The Voice") on Twitter.

"We are horrified and deeply saddened over the unconscionable murder last night of Christina Grimmie. She was poised to be one of the Philadelphia area's next global music ambassadors, but her star shined all too briefly." — Alan Rubens (board chairman of the Philadelphia Music Alliance) in a statement.
