Meghan Trainor has increased security following Christina Grimmie's death.

The 22-year-old singer was gunned down by obsessed fan Kevin James Loibl after a concert performance earlier this month, and All About That Bass hitmaker Trainor admitted that the tragedy left her in fear for her own safety.

She explained to the New York Post's Page Six: "The two days following [Grimmie's murder] I was like, 'I'm not going out to see fans, I'm too afraid now.'

"I want to make sure we have good security. I'm not that artist yet, I don't have security with me all the time, I don't have 'my guy.' I asked my team, 'Should I be getting a guy? Should I have someone?' I go out all the time without security, and you just never know. You have no idea who's out there obsessed with you to the point that they would do something like that.

"I did go out recently and sign [autographs] for some fans... and I do feel better about this. I do need to be careful, but I can still do this. I don't have to be afraid of the world. That's my biggest fear on top of that, to be afraid to go outside."

Christina had opened for the band Before You Exit at The Plaza Live in Orlando and stayed on afterwards to sign autographs for fans when Loibl - who was carrying two handguns, two loaded magazines and a hunting knife - approached her and opened fire.

Police believe he came to the gig with the intention of killing Christina.

The police chief added: "He came here to commit this crime and had plans to travel back to where he came from."

However, after Christina's brother tackled Loibl, the murderer killed himself.
