James Packer

Mariah Carey reportedly acts like a diva at dinner with fiancé

Diners at the famed Ristorante Aurora were stunned when, after a quiet dinner on Sunday, at 11 p.m. a loud Mariah song suddenly blasted, and in walked the star with her fiancé, James Packer, in tow.

“She literally had an entrance song,” our spy marveled.

Carey was “charismatic,” telling stories and having a blast with a group of 10 people, including Uma Thurman’s ex Arki Busson.
