Bebe Rexha's Curves in Croatia ... 'In the Name of Love'

"Bebe??" More Like "Bae-be!!!"

Bebe Rexha recently vacay'd in Croatia ... and based on the bootylicious pics, she got her daily dose of Vitamin Sea, with her bikini buns on blast. The sexy singer hit the back of the boat for a quick photo sesh before headin' deep!

Rexha showed off her backside to her millions, clearly she's lettin' loose on her getaway and lettin' blonde locks flow freely ...

Back on the shore, the 35-year-old donned a form-fitting dress and posed pretty on the patio.
