Insiders tells the news site Packer has been pursuing Mariah ever since her marriage to rapper and entertainer Nick Cannon fell apart last year (14).

Carey was briefly linked to moviemaker Brett Ratner, a friend of the billionaire, earlier this year (15), but she insisted the director is just a good friend.

Packer's ex-girlfriends include Tania Bryer, Joan Severance and Deni Hines. He was married to swimsuit model Jodhi Meares and model and singer Erica Baxter, with whom he shares three children. The couple separated in 2013.
