Camila Mendes rang in the new year by loving on her boyfriend, Rudy Mancuso.

The “Riverdale” star, 28, and the YouTuber, 30, were seen enjoying New Year’s Day in Miami Beach, where paparazzi caught the pair packing on the PDA in their first public sighting as an official couple.

Mendes sported a white bikini with floral patterns, while Mancuso opted for lilac swim trunks.

The “Música” co-stars, both of whom are Brazilian, could not keep their hands off each other in the water or on the sand.

At one point, Mendes wrapped her arms around Mancuso as the two smiled, laughed and enjoyed the waves.

The “Awkward Puppets” creator then hugged the actress from behind while giving her kisses on her neck and cheek.

Mendes looked festive during the outing, sporting a New Year’s hat and headband at different times throughout the afternoon.

She was later seen sitting on a lounge chair while sipping on a beverage.

The “Do Revenge” star soft-launched her relationship in early November 2022 with a cheeky Instagram carousel that showed glimpses of Mancuso.

“Life update,” she captioned a series of seven photos, two of which featured her now-confirmed beau.

Mancuso opted for lilac swim trunks.

The first image showed the shaggy-haired former Vine star sitting on the floor by a front door while playing with Mendes’ dog: a Maltipoo named Truffle.

The second snap was a selfie of the twosome taken in the reflection of a sliding glass door that showed Mancuso giving his leading lady a smooch on the head.

Not only are they co-stars, but Mendes and Mancuso are also both executive producers on “Música” — a modern-day rom-com co-written and directed by the funnyman.

It appears they may have fallen for each other on the set.

Mendes first posted Mancuso on social media in early November 2022.

After spending last summer filming together in New Jersey, Mancuso wasphotographed arriving in Italywith Mendes ahead of the 2022 Venice Film Festival in September.

The duo were then seen leaving a Halloween party together,according to Just Jared Jr.

Mendes previously dated her “Riverdale” co-star Charles Meltonwhile Mancuso was last linked to actress Maia Mitchell.
