Demi Lovato said that she 'loves going on adventures' with boyfriend Max Ehrich. Here's a complete timeline of their relationship.

"I was on dating apps for a while, but as I've spent some time with myself over the past couple months, I realized that I am the type of person that will find any way to regulate when I'm sad or lonely or whatever," Lovato said during an appearance on "The Ellen DeGeneres Show."

She added: "I have to fight those battles on my own, and I can't let somebody come in and fix those issues for me. So right now I'm single and spending my Saturday nights by myself."

She also spoke about her relationship status in a cover story for the May 2020 issue of Harper's Bazaar.

"I've never felt more loved," Lovato said during the interview, which was conducted in early March. "Which is really cool because I'm single as all hell right now."

The "Skyscraper" singer's previous relationship with model Austin Wilson reportedly ended in December 2019 after a few months.

Ehrich alluded to their relationship throughout March by posting graffiti of Albert Einstein holding a "love is the answer" sign, sharing poems about love, and dedicating a post to "mi armor" (which translates to "my love") — all of which Lovato liked on Instagram.

The "Confident" singer also began writing flirty comments on his photos.

In response to a shirtless photo of Ehrich, which he captioned "when u realize u should've packed more for your quarantine stay," Lovato wrote: "Fine by me..."

On March 24, Ehrich posted a black-and-white video of himself singing Coldplay's "Yellow" while playing the piano. In his caption, he wrote: "4D," followed by a rose emoji and a heart, presumably dedicating the cover to Lovato.

It's unclear how or when the two stars began dating, but an unnamed source told Us Weekly that they "met a few weeks ago."

People and E! News also confirmed that they were dating, with the latter publication reporting that Lovato and Ehrich "have been seeing each other for a few weeks now" and were quarantined together amid the spread of the coronavirus.

A source told E! News that Ehrich was "a good influence on Demi, and they have a lot in common," in addition to having mutual friends.

During the Instagram live, Ehrich was seated at a piano when Lovato approached, unaware that he was recording. He whispered, "I'm on live," and she quickly covered herself with her blanket and ran out of the frame.

Since Ehrich began staying with Lovato, they've both been posting plenty of photos with each other (and with Lovato's dogs named Batman and Cinderella) or images they've snapped of the other person.

The stars also frequently comment on each other's posts and have been spotted on grocery runs together.

A source told E! News that "they've really gotten to know each other on a different level" since self-isolating together.

"She is feeling great and loves being with him," the source added. "He supports her sobriety and is very understanding. It's going great and they both see it moving in a serious direction. She has loved having him at her house and trying out living together. So far, it's working very well."

The source also shot down engagement speculation, saying, "It's still early in the relationship and Demi and Max are enjoying just getting to know each other."

The video, which included celebrity cameos and fan-submitted footage, was released on May 8, 2020, with the money from the track benefiting the First Responders Children's Foundation.

Lovato posted a snippet of the music video on her Instagram and wrote: "Happy to be a part of something so special right now. Like really REALLY happy if you can't tell..."

Meanwhile, Ehrich wrote, "my whole heart."

In December 2011, the "Sweet/Vicious" actor tweeted: "All I wanted for Christmas was Demi Lovato. #cantalwaysgetwhatyouwant...."

In May 2020, Lovato posted a screenshot of the tweet on her Instagram story and wrote, "We love a little manifestation."

"Her family really likes him," a source told the publication. "He'll likely propose within the next couple of months, but when quarantine is over."

The source added that "Demi has been aware and in on the fact that Max wants to propose and is so excited."

"Had an amazing weekend in the magical desert of Joshua Tree with my love @maxehrich," Lovato wrote on Instagram. "I went to work on a project but it was so nice to get away for a couple days.. thank you for making me so happy my dear.. I love going on adventures with you."

She also gave a shout-out to her security guard for "bein our third wheel" and snapping all the photos of the couple.

Ehrich posted similar photos on his Instagram account, writing: "magical weekend in Joshua Tree with the love of my life."

He also revealed that one of the photos of the couple is now the lock screen image on his phone.

The "I Love Me" singer posted a series of images on Instagram and wrote: "Being with you makes life SO MUCH FUN. We literally act like hooligans on the daily and don't give a F--- if we're embarrassing ourselves if others are around!!"

Lovato continued: "I spend my days with you, bare faced and in a bathing suit.. I feel unconditionally loved and accepted by you in a way that I've never felt before.. I can't explain it or you.. you're indescribable, you beautiful, man. Inside and out you are jaw-droppingly gorgeous.."

She also said that the actor is "such a positive lil beam of light in my life."
