It's too hot in Cartegena....must jump in pool! @belussostyle #NewYears

Summer is heating up!
Bikini season is in full force -- and we have the snaps to prove it. Stars like Rihanna, Bar Refaeli, Lupita Nyong'o and more are celebrating summer through Instagram.
Bride-to-be Bar Refaeli recently posted a sexy pre-wedding poolside shot. The Israeli model, 30, rocked a skimpy two-piece (get the look for less: top and bottom) with a bachelorette sash, sunnies and a veil.
Rihanna may be the reigning queen of swimwear, though. The "B**ch Better Have My Money" singer rocked a strappy bikini with a gold bodychain, bangles and ultra-cool sunnies (check out this similar style). The pièce de résistance? A monkey hugging her chest.
See their looks and more sexy bikini snaps in the slideshow above.
