The 'Obsessed' singer was allegedly furious the hotel heiress had been asked to join her for an appearance in a music video for Prince Azim of Brunei – so she demanded he chose between the two of them.

Mariah reportedly said: 'It's either me or her. I won't do it with her. I'm a bigger name.'

The 40-year-old pop star is now due to appear in 27-year-old Azim's upcoming solo single alone.

The billionaire playboy – who is the son of the Sultan of Brunei – had originally wanted to improve the track's chances of success by having both beauties join him for the video.

But after Mariah made her demands, he had no choice but to ditch Paris, 28.

Azim has since promised to fly the diva and 14 members of her entourage over to London from New York by private jet.

The pop diva has been friends with the prince – who is fourth in line to the throne – for several years.

In 2006, he gave her a $5.7 million necklace and matching ring after flying to see her in his private jet.
