Billionaire James Packer and his songstress girlfriend, Mariah Carey, were caught “motor-boating” on his yacht.

They’ve been holidaying around Italy all week, and they were openly canoodling on deck with Packer getting a face full of cleavage… You can see all of the pics here.

There’s been talk of marriage between the two, who have only been dating for a short time.
