XOMG POP! is being showered with praise from JoJo Siwa.

On Tuesday night, the girl group delivered a colorful and energetic performance at America’s Got Talent‘s latest live shows, singing their new original song “Merry Go Round.”

Following the performance, JoJo — who was in the audience to support the group she created with her mother Jessalynn Siwa — spoke to PEOPLE backstage about their efforts.

Describing how she felt after watching the young ladies perform, the 19-year-old Dance Moms alum told PEOPLE exclusively: “Unreal, proud mom, proud older sister, proud best friend, proud mentor, all of it.”

“They took what I gave them, took what my mom gave them, and ran with it and made it bigger and better than we could have ever imagined,” she added.
