Adam added: 'This is yet another senseless act of extreme violence. I am left stunned and confused how these things can conceivably continue to happen in our world.'

The Maroon 5 frontman's fellow coaches joined him in sharing their grief at the devastating news.

Blake Shelton tweeted: 'I'm stunned and disgusted and heartbroken that we lost that sweet little girl... Keeping @TheRealGrimmie family in my heart and mind.'

Carson Daly, who hosts the show, called into The Today Show on Saturday and said that he and the rest of the team are 'all still in shock'.

He went on: 'We’re all saddened by the news of Christina, who was just an incredible talent, and incredible person.

'People say the phrase a lot, "so-and-so was a nice person." Christina really was, she was special. She would walk in a room and have an infectious laugh. She was determined; she was confident. But she was so incredibly sweet.'

Carson added: '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 tragedy that much harder this morning.'

Police believe that Christina's death was a targeted attack, but the killer did not know her. 

The star's brother Mark tackled the 27-year-old gunman after he shot Christina in the head, preventing him from injuring anyone else. The gunman then shot himself dead.
