US celebrity gossip website TMZ published a series of photographs of the pair strolling around the Italian island, where they were said to be holidaying on Packer’s yacht.

“The guy is James Packer, a 47-year-old entertainment mogul who sold a media company and now owns a string of hotels and casinos around Australia and other countries. He’s worth an estimated $4.6 billion, according to Forbes,” TMZ reported, and included a photo gallery of Packer over the years.

Carey has separated from husband Nick Cannon, with whom she has young twin sons.

Packer has three children with his second wife, Australian model Erica Packer, from whom he separated in 2013.
