Demi Lovato found it "really healing" to perform with the Jonas Brothers over the weekend

Speaking on the Chicks in the Office podcast, she said: "[Joe] was like, 'Hey, what are you doing next weekend on the 10th? We would love to have you come and perform This Is Me and Wouldn't Change a Thing. You've been a huge part of our journey and ... this show is really important to us and we would love to have you there.

"It was so nice. We've been through so much together, all of us, the Jonas Brothers and I, and it was really, really great to spend time with them.

"They came to my room all three of them and spent time getting to know my husband, which was really meaningful to me.

"And they just 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. I loved it. Every second of it was so great."

Demi admitted she had no hesitation in agreeing to the performance because not only has she come to a point where she's happy to embrace her past, she was particularly happy to revisit a very "meaningful" song.

She said: "This Is Me is my first big song that I've ever had. So getting to perform that with them for the first time in God knows how many years was just so full circle and so special and it was great to see them."

However, the singer needed some help remembering the lyrics to This Is Me before she got on stage.

She said: "Once I listened to it a few times, it all came back to me," she said. "We finished soundcheck and Joe was like, 'Yeah, we still got it.'"

Demi also returned to the Camp Rock movies after learning one of her closest friends had never seen Camp Rock 2: The Final Jam.

She said: "I was like, 'B****, we're watching it.' So we watched the first one and I cringed out of my soul, but I loved every second.

"And we watched the second one the next night, and it was so fun.

"I don't just see a project that I worked on, I see a collection of memories that really fulfilled me and gave me so much life at a dark point in my life. I was kind of struggling when I was working on those projects but those projects brought me so much joy."
