Rihanna looooves to be photographed ... and we love that she loves it!

BadGalRiRi was looking super hot in a teeny-weeny bikini Sunday in Barbados and she had no problem showing off her smokin' hot body in front of photographers and tourists alike.

Meanwhile ... Rihanna might look all sex and sand in these photos, but there's some darker stuff going on in her head, apparently ...

She Instagramed this message on Saturday -- is it a message to her ex, Chris Brown?

Regardless, the singer will ring in the new year in NYC at her mentor, Jay-Z's club, 40/40. Who will she kiss at midnight???
