Mariah Carey's daughter steals spotlight from mum

Mariah Carey's daughter has stolen the spotlight from her famous mother, after the singer brought the cute six-year-old onstage for a duet at one of her concerts.

TMZ has obtained video of the adorable sing-off between the singer and the little diva-in-making, Monroe.

In it, Mariah can be heard singing her hit 'Always Be My Baby' while her daughter stands beside her.

She then bends down to stand at eye-level with her daughter and shares the microphone with her.

At the first the little girl appears shy but she soon opens up and begins singing along with her mother.

SAH CUTE!

Monroe's twin bother Moroccan was also onstage at the time but he kept quiet - no doubt saving his voice for a solo debut!

The twins' dad Nick Cannon has previously spoken about their love for the limelight.

The 36-year-old told E! News that they'd contracted the entertainment 'bug'.

"My kids, especially Moroccan and Monroe, they're hams," he laughed. "They love attention. They love performing. My son is fascinated with cameras and directing and making little movies. They definitely have the bug."
