Camila Cabello and her new man are back at the beach … going for a quick dip together after their wet and wild make-out sesh earlier this week.

The singer-songwriter hit the beach with Henry Junior Chalhoub in Ibiza Tuesday … emerging from the water in their form-fitting bathing suits.

Camila put onlookers in a “Better Place” with her tiny white bikini … drawing eyes and dropping jaws while prancing around the waves.

Chalhoub’s not looking too bad himself in his red and black shorts … showing off his strong, hairy chest while following Camila back to the shore.

There’s no touching in these pics … but, we know these two are crazy about one another — ’cause on Monday, they were locking lips in a wet embrace while floating through the water.

Chaloub — a billionaire heir, BTW — was all over Camila in the snaps … and with how she pulls off swimwear, it’s not hard to see why.
