Newly engaged Dua Lipa and Callum Turner are so steamy together … they needed the ocean to help cool them down!

The pop star and her fiancé were snapped pouring on the PDA while they were all loved up on a raft along Italy’s Amalfi Coast … all between plunges into the crystal-clear Mediterranean waters.

As for Dua … we sure hope she used plenty of sunscreen, ’cause she was rockin’ a skimpy polka dot bikini — leaving lots of skin exposed and very little to the imagination.

The fire couple announced their engagement earlier this month … spilling the exciting tea to British Vogue when Dua revealed her engagement ring was custom-made after Callum consulted her best friends and her sister.

The “One Kiss” singer said they’re just soaking in the engagement vibes for now — no wedding planning yet. She’s focused on her tour, and Callum’s busy filming.

The exact timing of the engagement is a mystery, but the pair — who started dating in Jan ’24 — had everyone talking by the end of the year after Dua was spotted rocking a ring on that finger.
