NEW YORK (AP) — Mariah Carey is hoping her third walk down the aisle will be the one. She is engaged to Australian billionaire James Packer. Her representative says they got engaged in New York on Thursday. Carey’s divorce from Nick Cannon was finalized last April. Previously she was married to record executive Tommy Mottola. Carey has a boy and a girl from her marriage to Cannon. Packer was married twice before and has three kids. Forbes magazine says Packer’s net worth is $3.5 billion, making him the fourth richest person in Australia.
