The 45-year-old singer is currently filming a documentary-style series to allow her fans to go behind the scenes of her Las Vegas residency, reported UsWeekly.
The show will also follow Mariah on her world tour, which is due to end in May.
"It's nuts, she is very funny on camera," a source said.
The show will be called "Mariah's Squad" and will give music fans a real insight into her life as one of the biggest music stars in the world.
A date for the series to air is yet to be revealed.
