While Demi Lovato‘s fans, family, and friends continue to process the devastating news of her apparent overdose, the famed singer has officially entered a rehab center to receive treatment for her mental health, according to Radar Online. Prior to her relocation to Arizona, the 25-year-old was being treated at Cedars-Sinai Medical Center in LA, where she received an outpouring amount of support from everyone in her life, including ex-boyfriend Wilmer Valderrama.

“Wilmer went into a state of shock and was hysterical when he found out about Demi overdosing,” a source tells Life & Style exclusively. “He’s been standing vigil every day for hours on end.” Naturally, Wilmer’s role in his ex-girlfriend’s recovery has brought them closer together. So much so, that the ex lovers have “already discussed getting back together,” the insider reveals. However, there’s “one condition: Demi has to be completely clean and sober.”

The pair dated for a whopping six years before calling it quits back in 2016. “After almost [six] loving and wonderful years together, we have decided to end our relationship,” Demi, then 23, wrote. “This was an incredibly difficult decision for both of us, but we have realized more than anything that we are better as best friends. We will always be supportive of one another.” With that, Wilmer and Demi have been spotted together many times since their split, including on Demi’s 25th birthday. 

In addition to Wilmer, many celebrities have shown their support by reaching out via social media to send their prayers and well-wishes. From Ariana Grande, to Lady Gaga, to Demi’s longtime friends Nick Jonas and Joe Jonas, it seems all of Hollywood has banned together to send their regards to the struggling starlet. “Like all of you I am reeling at the news about Demi. All of us love her and need to pray for her to get well. She is a fighter. #prayfordemi,” Nick shared on Twitter.

On Sunday, Aug. 5, Demi broke her silence on her apparent overdose to send a message to her friends, family, and fans: “I have always been transparent about my journey with addiction,” Demi wrote on Instagram. “What I’ve learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet. I want to thank God for keeping me alive and well. To my fans, I am forever grateful for all of your love and support throughout this past week and beyond. Your positive thoughts and prayers have helped me navigate through this difficult time.” 

She continued, “I want to thank my family, my team, and the staff at Cedars-Sinai who have been by my side this entire time. Without them, I wouldn’t be here writing this letter to all of you. I now need time to heal and focus on my sobriety and road to recovery. The love you have all shown me will never be forgotten and I look forward to the day where I can say I came out on the other side. I will keep fighting.”
