Washington, August 6 Mariah Carey and hubby Nick Cannon expressed their love for each other on stage during an episode of America's Got Talent.

The singer's spouse who host the show welcomed her wife for a special performance.

"Make some noise for the amazing Mariah Carey!" Contactmusic quoted him as saying.

The singer sang her new single Obsession with a troupe of backing dancers performing alongside a dazzling light show.

After she finished Canon reappeared to embrace and declare his love for her.

He said: "I am obsessed with this beautiful girl right here. It's all about Mariah."
