Demi Lovato's ex Joe Jonas joins masses of celebs sending support after reported overdose

Demi Lovato's ex-boyfriend Joe Jonas has joined the growing number of celebrities sending her support after she was rushed to hospital for a suspected drug overdose.

The lead singer of the band DNCE took to Twitter to share his condolences.

"Like all of you I am thinking of @DDLovato right now. She needs our prayers and support. We all know how strong you are Demi. #prayfordemi," he wrote.

His sentiments were echoed by his brother Nick Jonas, who also remains Lovato's close friend. 

Lovato and Joe Jonas met while starring opposite each other in the 2008 movie Camp Rock. They started dating in 2010, before splitting that same year.

At the time, Jonas told People, "It was my choice to break up, but I love her as a friend. She's been there for me when I needed her. I will continue to be her friend and be there for her."

The Jonas brothers' messages are just two of a huge outpouring of support for Lovato from other celebrities online.

"We should all wrap our arms of love around Demi Lovato," wrote fellow pop star Lady Gaga.

"I am so happy you're alive. Thank God."

TV host and former supermodel Tyra Banks reminded her followers, "addiction is not a choice".

Ariana Grande simply told Lovato she loved her, while Ellen DeGeneres said she was heartbroken by the news.

"I love @DDLovato so much. It breaks my heart that she is going through this," DeGeneres tweeted.

"She is a light in this world, and I am sending my love to her and her family."

Riverdale actress Lili Reinheart cited the 'Skyscraper' singer as an inspiration to her growing up, due to her transparency about her struggles with depression.

"When I was 14, she was an idol to me in how she spoke so openly about mental health," said Reinheart.

"And now she continues to inspire thousands of young men and women with her body positivity messages. Addiction and mental illness doesn't discriminate."

Rapper Macklemore and singer Charlie Puth both dedicated songs to Lovato during their concerts following the news of her hospitalisation. 

The hashtag #PrayforDemi is currently trending on Twitter.
