When Mariah Carey goes yachting, there's no need for a swimsuit.

While the songstress vacationed in Italy this week, she shared several shots of herself aboard a yacht wearing nothing more than an off-white lingerie slip and a diamond necklace. "Pon de ocean," Carey captioned one photo that showed her flashing her massive engagement ring and leaning over a wooden railing as she enjoyed a picturesque view of the ocean.

In another snap from her impromptu yacht photo shoot in Ponza, Carey hugs her torso with one arm, showing off her blinged-out bangles, and clutches her shades with her other hand. The "We Belong Together" singer's wavy hair is pulled back and she is glowing while gazing out onto the water.

Carey posted several more shots of herself in the slip dress, including a close-up where she flashes a smize and clutches her blonde locks. The singer has been enjoying the sights and sounds of Italy with her husband-to-be, James Packer, and her two children, Moroccan and Monroe, following her performance at the Essence Festival in New Orleans last week.

In a sweet snap, the adorable 5-year-old twins give mom kisses on the cheek, with Carey clad in white ripped jeans, a white top and black wedges. Little Moroccan's curly hair flows as he leans in to smooch his mama in a printed denim-button down and white shorts, and Monroe joins in on the smoochfest in a navy and white striped dress.

Like their mom, these two appear to love a good photo opp, so they were all smiles as they struck solo poses for Carey's 'gram, with Monroe putting her ice cream treat on display and Moroccan showing off his cool pose in shades.

This mom knows how to kick the summer off right.
