Watch as the cast of ‘The Walking Dead’ sing ‘Happy Birthday’ to Demi Lovato

The singer shared the clip on her Snapchat

The cast of The Walking Dead have sent Demi Lovato a special birthday message.

The singer shared the clip of Andrew Lincoln and Norman Reedus singing ‘Happy Birthday’ to her on her Snapchat.

Lovato, who was celebrating her 24th birthday, also tweeted about the video, as Billboard reports.

“I just got the best birthday video sent from the cast of the walking dead and I’m shitting my pants,” she wrote.

Earlier this year, Lovato revealed she thought she was destined for an early death as she had undiagnosed mental health problems when she was a teenager.

Lovato’s engineer father Patrick has bi-polar disorder and her ex-cheerleader mother Dianna was bulimic. Lovato said: “Being around somebody who had an active eating disorder and weighted 80lbs, it’s hard not to grow up like that.”

The singer began self-harming and binge-eating aged nine and said she became addicted to cocaine, alcohol and prescription drugs aged 15 when she starred in her own show Sonny With A Chance on The Disney Channel. Lovato said: “I lived fast and I was going to die young. I didn’t think I would make it to 21.”

Lovato, whose most recent album was ‘Confident’ in 2015, said she tries to discuss mental health issues with her fans at meet-and-greets before her gigs. The 23-year-old said: “I can’t tell you the amount of times girls will show me their arms covered in cuts or scars. They tell me ‘You helped get me through this.’ Hearing these things gives my life new meaning.”
