Demi Lovato brings out JoJo and Jutes during surprise-filled Madison Square Garden concert

The singer also announced a deluxe version of her latest album.

Demi Lovato packed several headline-making moments into her Friday concert at Madison Square Garden, where the singer brought out surprise guests JoJo and husband Jutes during a sold-out stop on her "It’s Not That Deep Tour."

The surprise appearances came just hours after Lovato released "It’s Not That Deep (Unless You Want It To Be)," a deluxe expansion of her latest album featuring eight new tracks.

During the middle of the show, Lovato welcomed JoJo to the stage for a performance of "Too Little Too Late."

Videos shared online showed the crowd erupting as the two singers traded vocals on the track.

Lovato later acknowledged the buzzy moment on social media, reposting Instagram Stories from fellow artists including Kelsea Ballerini and Adam Lambert, both of whom shared clips of the performance.

Later in the set, Lovato shifted gears when she brought out Jutes for a performance of "Iris" by Goo Goo Dolls.

After the concert, Lovato posted a video of the performance to Instagram and captioned it, "you & me forever @jutesmusic," while tagging Madison Square Garden.

"Falling in love with him changed my sound," Lovato told Nightline back in Oct. "I was like 'I'm gonna go make another rock album' and as I was making it I was (like) 'wait, I'm really happy.'"

Lovato is currently on tour through the end of May with stops scheduled in Houston, Seattle and more.
