Demi Lovato took to Twitter to speak about mental health awareness following the "All About That Bass" singer Meghan Trainor's comments about her lifelong struggle with weight.

The hit singer Meghan, whose empowering song is still No. 2 on the Billboard Hot 100, spoke to Entertainment Tonight her life.

"I grew up a chubby girl," she said. "My parents loved us, they fed us whatever we wanted."

She talked about her crush saying to her, "You'd be like real hot if you were 10 pounds lighter." Trainor said she cried and did not eat for the rest of the day when she heard that.

"I wasn't strong enough to have an eating disorder. I tried to go anorexic for a good three hours," she said.

"I ate ice and celery, but that's not even anorexic. And I quit. I was like, 'Ma, can you make me a sandwich? Like, immediately.'"

Former Disney actress Demi Lovato took to Twitter to say, "Having an eating disorder doesn't show "strength." Strength is when you are able to overcome your demons after being sick and tired for so long."

The singer who also suffered from an eating disorder in the past tweeted, "There's a wide misconception that anorexia and/or bulimia is a choice and you often hear people say things like "why doesn't she just start eating?" Or even "just stop throwing up."

She added, "It's the ignorance and lack of education on mental illnesses that continues to put mental health care on the back burner to Congress even though this is an epidemic that is sweeping our nation, and causing more and more tragedy every day."

The star, who recalls having low body confidence since she was three years old said, "Starving is not a "diet" and throwing up isn't something that only extremely thin men or women do. Eating disorders do not discriminate."

Demo Lovato opened up about getting help two years ago.
