Mariah Carey's reality TV show 'up in the air'

Mariah Carey's reality TV show 'up in the air'

Mariah Carey's new reality TV show is "up in the air" following her recent split from James Packer.

The 46-year-old pop star's forthcoming series 'Mariah's World' is set to hit television screens on December 4 but executives at E!, the network that will broadcast the programme, are concerned that she'll demand the whole thing be pulled after she ended her engagement with the billionaire in Greece this month.

A source told "Now that the engagement is off, E! is freaking out. The network had hoped Mariah's journey to marriage would draw in viewers, but now there's fear that much of the key footage with James and the wedding plotline is irrelevant [now they've split]."

And, although the main focus of the show is on the 'Hero' hitmaker's highly successful career, it's believed their shock break up stemmed from James' reservations about exposing their relationship to the cameras.

A source said recently: "James had huge reservations about Mariah's new reality TV show and the fact that she was willing to expose their lives to the world ... James is very generous, but Mariah takes it to the next level."

The couple - who began dating in June 2015 and announced their engagement in January this year - came to blows a few weeks ago during a trip to Southeastern Europe and haven't seen each other face-to-face since.

However, the pair have agreed to work through their differences over the next coming weeks and see if they can make their relationship work.

A representative for Mariah said: "Mariah and James had a fight in Greece, and have not seen each other since. [The fight was not due to] any cheating allegations or excessive spending. They are trying to work it out. Right now, they're not sure if they will stay together. They are discussing it."

Although their relationship is currently in limbo, Mariah isn't ready to give up on her Australian beau just yet as she's still wearing the $10 million engagement ring he gave when he got down on bent knee 10 months ago.

Meanwhile, this isn't the first publicised break up the brunette beauty has experienced in recent years as she also had to watch her split from Nick Cannon, with whom she has five-year-old twins Moroccan and Monroe - play out before her eyes in August 2014 following six years of marriage.

The 36-year-old 'America's Got Talent' host filed for divorce shortly after they went their separate ways but it's yet to be finalised in court.
