Mariah Carey's children will feature on her next album.

The '#Beautiful' singer - who has two-year-old twins Monroe and Morocco with husband Nick Cannon - has revealed her children sang on her track 'Supernatural', which will be included on the upcoming record.

Mariah told Wonderland magazine: ''There's a song on the record called 'Supernatural' that I haven't talked to the media about before - it features Roc and Roe.

''Especially Monroe - that's her song. She opens the song, actually. It was something along the lines of 'Goo goo goooo.'''

Mariah has become famed for her eight octave vocal range, and it now looks as though her daughter Morocco is following in her footsteps, as she revealed the tot has a strong voice.

The 44-year-old pop star added: ''For a two and a half year old, she was a steady vibrato.''

Meanwhile, Mariah's record label have denied reports she is planning to put a surprise album online after Beyonce's released her album digitally without any marketing or advertising in December last year.

Def Jam's Executive Vice President, Darrale Jones, said: ''Mariah will announce the date and title in advance of the on-sale date.''

The label executive also confirmed the album is due for release next month.
