James Packer is playing Mariah Carey's greatest hits on repeat in his hotels.

It’s no secret now that billionaire entrepreneur James Packer and singing sensation Mariah Carey have been dating for months now.

They’ve been seen canoodling in expensive restaurants, taking Mariah’s children out for Halloween, and attending red carpet events together. And while it may be an unexpected pairing, they appear to be very happy.

But the staff and patrons at Packer's Crown Casino in Perth are less happy.

Mainly because James has instructed that his current flame Mariah be played on repeat in the Casino's entertainment quarters, Fairfax reports.

Literally, non-stop carolling and high notes.

Think "Hero" when you win a hand of Blackjack, "Endless Love" as you drink your fifth white wine spritzer, and don't you know "When You Believe" will be blasting in the private bathrooms.

It's either your dream or your worst nightmare.

We hope they at least swap to the Christmas album when the time comes.
