International songstress Demi Lovato has urged Paris Jackson to "stay strong" in the wake of her suicide attempt.

The 15-year-old daughter of late superstar Michael Jackson was rushed to hospital earlier this week after she attempted to take her own life.

Lovato - who has been open about her struggles with depression and self harm in the past - took to Twitter today to offer some words of encouragement to the vulnerable teenage star.

She wrote: "Dear Paris Jackson, don't let bullies to let you down. We believe in you!! Stay strong, Please ... You're beautiful and we love you. #Praying (sic)."

Lovato sought treatment for her struggles, and admitted in an interview last year: “There were times I felt so anxious, almost like I was crawling out of my skin, that if I didn’t do something physical to match the way I felt inside, I would explode. I cut myself to take my mind off that. I just didn’t care what happened. I had no fear.”

Paris has received an abundance of well wishes from a host of famous faces, including Keri Hilson and Alyssa Milano.

While Hilson wrote: "Life will turn around. God, please give this young girl the peace in her heart until that time... #ParisJackson," Milano tweeted: "@parisjackson Sending you support and love (sic)."
