Mariah Carey Rocks pink swimsuit, hanging with kids on the Amalfi Coast

Mary Careyis heating up the Amalfi Coast, because even the Queen of Christmas needs a summer vacation… and she’s taking hers in a skin-tight pink swimsuit.

The singer-songwriter took to the water on Wednesday’s famed Italian coast … wearing a pink and black spandex suit with a plunging neckline that revealed her black bikini underneath.

Mimi got on a boat with her 13-year-old twins — Moroccan And Monroe – lazing around as they enjoyed the European sun, and Monroe put her arm around Mom.

The trio sailed along the pristine Italian coastline and admired the beautiful sights of the Mediterranean.

It’s a sweet little family vacation…obviously, without it Nick Cannon – the children’s father – who split with Mariah in 2014.

Remember these images in about 4 months. If you’re wondering where and how MC spends the reported $3 million she makes every year right before “All I Want for Christmas”… well, here it is!

BTW…she’s coming back with a 20 city Christmas tour in November for the 30th anniversary of her album “Merry Christmas.”
