In an adorable moment, Mariah brought them on stage to help her sing, "Always Be My baby."

"If they want to do that, I'll be happy for them," Mariah told "GMA" of the twins getting into show business. "Whatever they want to do, I'll be supportive."

Mariah said she's "very proud" of "Caution." But it isn't her only project making headlines. Just recently Mariah's 2001 album "Glitter" rose to No. 1 on the iTunes chart.

"That's the Lambs, that's the Lambily, those are my fans--they had this movement, it was called hashtag Justice for Glitter, which I think was directed at me because I never really perform those songs because it almost ruined my life," she said. "But the truth is, it's for the nostalgia now because it's actually a really good album."
