“Seriously, just trashed it. She ran out of the room screaming. So the night was obviously finished for James, and they retreated to separate parts of the house. And she had a few glasses of wine to cool down.

The site says this hasn’t been the only incident, claiming Mimi nearly lost her ish another time when her nemesis Jennifer Lopez came on once came on Packer’s system:

James nearly had a repeat performance of Mariah’s Beyonce-fuelled fit, courtesy of one of Jennifer Lopez’s early hits.

“He put on five bars of ‘Waiting for Tonight’, and Mariah coughed out her courgette at dinner so James made a bee line for the Spotify and immediately put on Mariah’s greatest hits!” our source added.

“He has learned never, ever to play another female artist in the house. It’s either Mariah, jazz or classical!”
