Grammys 2020: Demi Lovato bursts into tears in the comeback performance of her career

There wasn't a dry eye in the house after Demi Lovato's moving performance at the 2020 Grammys.

The star earned a standing ovation for her new song, 'Anyone', in her first live performance since entering rehab and going on a musical hiatus after a nearly-fatal overdose in July 2018.

TMZ reported earlier this week that the emotional ballad was written and recorded a mere four days before the overdose, which was clearly reflected in the heartbreaking lyrics and tone of the song.

Lovato restarted the song after erupting into tears but kept her composure and delivered a moving performance that was arguably one of the best of her career.

She took the stage in an all-white ensemble, featuring a long-sleeved ball gown and studded belt.

The star took to Instagram following her performance to pen an emotional note to fans and viewers:

"What an unbelievable night. My first time back on stage in almost 2 years," she wrote, "So emotional for me. Thank you all for the love, support and for sharing this moment with me. I love you all. 💗".

In an interview earlier this week with Apple Music's Zane Lowe, Lovato elaborated on the songwriting process and how listening to and performing the song now is a vessel through which she can measure the progress she's made in her recovery:

"At the time when I was recording it, I almost listened back and hear these lyrics as a cry for help ... I even think that I was recording it in a state of mind where I felt like I was okay, but clearly I wasn't. I even listened back to it and I'm like, 'Gosh, I wish I could go back in time and help that version of myself.' I feel like I was in denial."

The lyrics play to Lovato's struggle with faith and inability to feel truly seen ("I feel stupid when I pray, why the hell am I praying anyway if nobody's listening?") and how alone it can truly feel in the lowest moments ("Lord is there anyone? I need someone").

The singer also told Lowe that she's making sure to take necessary precautions to prepare herself for the aftershock that comes with such a huge comeback and performance, showing dedication to her journey of recovery and this next decade:

"Something I've dealt with in the past is having these really incredible experiences like the Grammys or tour or concerts or things like that. I have to be aware of like, okay, I'm going to crash because my adrenaline is going to go all weekend, and then I'm going to have this performance. Whether it goes great or not, my adrenaline is going to come crashing down come Monday morning … but it's important to plan ahead so ... come Monday after the Grammys, I'm not sitting there like twiddling my thumbs like, 'Okay, what am I doing with my life now? Where do I get this from? How can I beat that high?' Just be prepared.”

Lovato posted to her Instagram mere hours before the show and her performance in a tribute to Kobe Bryant:

"This makes me so sad. Kobe you were always so sweet to me," Lovato captioned the photo of herself with Bryant and his daughter GiGi, who passed away alongside her father in a helicopter crash Sunday afternoon.

"This whole family was so sweet and now they’re in my prayers heavy."
