They rang in the new year together at Melbourne after spending Christmas in the U.S. with her children.
And Mariah Carey and James Packer were every bit as loved-up as they jetted into Sydney with her children on Sunday for the day.
After a private flight on board the billionaire’s jet, the couple and Mariah’s four-year-old twins, Morocco and Monroe, were spotted mounting a boat in the city’s harbour.

After a day on the water the group then returned to James’s aircraft and flew out, no doubt on their way to another luxurious destination.
Mariah, 45, put on a glamorous display in a floor-length black dress which highlighted her newly slimmed down figure.
The songstress wore her blonde locks tied off her face in a sleek ponytail and wore a pair of large black sunglasses throughout.

She finished her dressed-up off-duty look with some chunky black high heels, teetering along a jetty towards the boat they would spend the day on.
Meanwhile James, who is also enjoying the results of recent weight loss, showed off his trim figure in jeans, a white t-shirt and a black blazer.
The casino mogul kept his sunglasses on as the group made their way around the harbour.
The couple and Mariah’s children were joined by an entourage which included one woman who was seen tending to the singer’s hair.
Another carried sleeping Monroe as her twin brother walked hand-in-hand with his mother.
Earlier in the week Mariah shared an adorable snap with her twins on board Packer’s jet, with the three snuggled in to a bed for their luxurious flight.
Mariah and her children are expected to join James at his family’s Ellerston estate in Scone in the upper Hunter Valley as the couple continue their extended break.
They spent Christmas in the upmarket ski resort of Aspen before ringing in the new year at his Crown casino in Melbourne where Mariah performed for revellers.
