There’s nothing holding Shawn Mendes back from putting his hands all over his new lady … because he was spotted getting close to his girl Bruna Marquezine!

The singer-songwriter hooked up with the Brazilian bombshell off the coast of Algagoas — a state in the Latin American country … eyes closed, lips tightly intertwined while they waded in the crystal clear water.

It ain’t easy to bring saltwater to a boil … but, these two certainly gave it their best shot with some passionate PDA.

Shawn and Bruna’s afternoon delight came just a couple weeks after we saw them leaving an airport in Brazil together … before they grabbed dinner at a Rio de Janeiro restaurant.

Bruna wore a tiny black dress to the occasion which left little to the imagination … while Shawn attempted to keep a low-profile in a black shirt and jeans.

The two have been traveling together a ton as of late … and, it looks like their relationship didn’t die with the stroke of midnight on New Year’s Eve.
