TMZ reported that Carey is dating the 47-year-old entertainment mogul just last week. Packer owns a string of hotels and casinos in Australia and is the fourth wealthiest person in the country. Earlier in his career, he sold a media company.

The couple was spotted in Capri, Italy, on Friday. It was rumored that they stayed on Packer's yacht for an "extended vacation" and are set to head to Cannes and St. Tropez after their time in Capri.

According to reports, Packer has been eyeing the "We Belong Together" singer for months after going to her concert in Las Vegas. He finally got to be with her when they were introduced by Brett Ratner.

Meanwhile, sources told TMZ that Carey and Packer are already talking marriage after dating for just a couple of days.

Yet, Carey is not officially divorced from Nick Cannon. She and Packer already look as though they were on a honeymoon while wearing matching robes on his yacht over the weekend.

As they cruised from country to country on his boat, Packer reportedly blasted Carey's music for everyone to hear.

According to People, Carey had her 4-year-old twins Monroe and Moroccan she shares with Cannon, and Packer brought along his three children he shares with ex Erica Baxter.

Sources tell People that the "brand new" relationship has "been bubbling for a couple of months."

Witnesses who spotted them eating Italian fare said that "they sat down and enjoyed their meal like any other romantic couple."

Carey is one of the most accomplished musicians holding the record for most No. 1 debuts in Billboard Hot 100 history, according to Biography.

She was signed to Columbia Records, later known as Sony, when she was 18 years old.
