Singer Demi Lovato described her recent reunion with the Jonas Brothers as a "healing" experience, as she reflected on her shared past and enduring friendship with the band she famously starred with in the Disney Channel movie "Camp Rock."

Lovato recently made a guest appearance on the kick-off show of the Jonas Brothers' "Jonas20: Greetings From Your Hometown" tour, treating fans to a nostalgic performance of "This Is Me" and "Wouldn't Change A Thing" from the "Camp Rock" films.

"It was so nice and like I said, it was so healing for me too, you know, we've been through so much together, all of us, the Jonas Brothers and I," Lovato said in a recent interview on the "Chicks in the Office" podcast, clips of which were shared Tuesday (Philippine time) on the podcast's TikTok account.

In the same interview, Lovato recalled how Joe Jonas, her "Camp Rock" leading man and ex-boyfriend in real life, approached her a week before the concert to invite her for the guest appearance.

"Honesty, Joe just asked me like last week, was like, 'Hey, what are you doing next weekend or on the 10th? We would love to have you come and perform 'This Is Me' and 'Wouldn't Change a Thing,'" she recounted.

"He was like, the show is really important to us and we would love to have you there," she added, quoting Joe.

Lovato said the reunion also allowed her to "spend time" with the trio, also comprising Kevin and Nick.

"They came to my room, all three of them, and like spent time getting to know my husband, which was really meaningful to me" she said, referring to musician Jordan "Jutes" Lutes whom the "Heart Attack" singer married in May.

"And they just, you know, thanked me profusely for flying across the country to perform with them and it was just so thoughtful and I felt so appreciated and it was really healing for us and I loved it," she added.

Released in 2008, "Camp Rock" catapulted Lovato to fame. She plays aspiring singer Mitchie Torres, who attends a summer music camp. The film's success led to a sequel, "Camp Rock 2: The Final Jam," in 2010.
