Demi Lovato will turn 21 years old in two months, and the former Disney star already shares her special birthday wish to her Twitter followers. A Barbie collector since she was a kid, she says it would be cool to have a realistic Barbie doll with her body type.

The female judge of "The X Factor (US)", who has been open about her struggle with body issue, bulimia and cutting, tweeted, "1 of my biggest dreams, having collected Barbies since I was a kid, is to have my own Barbie BUT with my actual body type...Weight & height."

"Lovatics!!! Blow up @BarbieStyle to make it happen!!!! That would be one dope 21st birthday!! Hahaha," she continued her plea for a not-so-perfect doll. "Also, Barbie should make dolls with cellulite!!! Hahaha!!! After all, around 95|percent| of ALL women have it!!!"

Just recently, Lovato revealed in an interview with Rolling Stone that she battled suicidal thoughts at the early age of 7, which is around the time she got the first taste in the spotlight as a star in "Barney & Friends". She said she was asked to sign a no-suicide contract.

She entered rehab in summer 2010 and has since actively campaigned to raise awareness and help her peers who's been having the same problems as her. She received a lot of recognitions for her work, including from the U.S. Department of Health.

Knowing all too well the pressure of handling the fame at a young age, Demi reached out to Paris Jackson after learning that the teen tried to kill herself. "Dear Paris Jackson, don't let bullies to let you down," she reportedly wrote to Michael Jackson's daughter, "We believe in you!! Stay strong, Please ... You're beautiful and we love you. #Praying."
