Last week, TMZ broke the news that Demi Lovato had been rushed to hospital following an alleged overdose. Sources reported that the 25-year-old was still unconscious when paramedics arrived at her home in the Hollywood Hills, but that she was eventually roused and treated with Narcan - an emergency treatment for overdoses with narcotic substances.

It was initially reported that the star had taken heroin; however, the Lovato's representatives later issued a statement saying that "Some of the information being reported is incorrect and [Lovato and her family] respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now."

Since then, little has been disclosed about the singer's condition, but now sources close to the singer have stated that there have been "complications" to her recovery.

"Demi wasn’t doing well over the weekend," one source close to the star told People. "She came down with a fever and showed signs of an infection. She is currently being treated for issues that are very common after a drug overdose. She will need to stay in the hospital for a few more days, but is expected to make a full recovery."

In the time that she's been in hospital, her friends and family have remained close by, with her ex-boyfriend - Wilmer Valderrama - apparently visiting every day.

"Wilmer is completely devastated and he still loves Demi and it was just a matter of scheduling and time that they needed to make a romantic relationship work," a friend of the singer told US Weekly. "She's been honest with him about her relapse, as she has with her family, friends, fans and the entire public, especially with her new song, but he didn't think it was this severe and that she would be struggling so much and have a situation that had these repercussions."

Despite the complications, Lovato is still expected to make a full recovery - though where she'll go after that is not yet certain. Her family have apparently been pushing for the singer to check in to rehab straight after she's been discharged from the hospital, as allowing anyone who has experienced an overdose to go home before seeking further medical help can interfere with long-term treatment.

Lovato has been to rehab before, back in 2010, and has spoken about her battles with mental health problems and alcoholism in the time since.

In March this year, though, she stopped a gig to give a speech that implied she had found her way back onto the wagon.

"I made changes in my life, and the reason I became so open about my story is because I know that there are people here tonight that need to ask for help, and I want you to know that that’s okay," she said at the time, adding: "I take care of myself. And I can never say ‘Thank you’ enough to you guys for the support that you’ve given me over the years, and you’ve forgiven me for my mistakes."

Though the 25-year-old is clearly in a low place again at the moment, she should follow her own previous mantra and forgive herself for this "mistake". Addiction is a serious problem, and Lovato could certainly do with all the support she can get right now.
