Hailey Bieber served up lemon sweetness in Mallorca, Spain, in an eye-popping Pucci bikini.

In photos shared to Instagram on Wednesday, the Rhode Skin founder soaked up the sun in the custom yellow-and-white thong bikini by Camille Miceli while relaxing on a boat.

“Summer club lemontini girli,” she captioned the carousel.
