And Rihanna proved she is wild for the night as she was spotted having a late night splash about with friends in the Brazilian water.
The 26-year-old showed off her slender bikini body in colourful, multi-print crop top which she teamed leopard print bikini bottoms.
Rihanna and her close pal, Jennifer Rosales, opted to take a dip in the water while the rest of the group looked on.
She was sure to keep her face dry as she wore natural looking make-up completed with a small flick of black eyeliner, while her wavy black weave was left flowing over her shoulders.
Rihanna shared snap from the night with fans as she wrote: ‘Ain't nobody better than me and my Jhat’.
One can only hope the singer’s midnight swim won’t come back to haunt her as it is a well-known fact that a lot of Rio’s waters face a lot of pollution issues.
In fact, many of the waters off of Rio’s shorelines are so polluted that they are deemed unsuitable for swimming but Rihanna and her fearless gang were willing to take the risk.
The government has been taking steps to deal with environment issue to perhaps Rihanna will be able to stay unapologetic about her sea swim.
Earlier in the week Rihanna stayed true to her party loving form on Friday as she jetted into Rio de Janeiro, Brazil, ahead of Sunday's World Cup final.
Not even in the country for an hour, the 26-year-old cracked open a beer and gave a cheers to the soccer-mad city from her stunning penthouse hotel room.
Flown into town by alcohol company Budweiser, the star happily indulged in her sponsor's libations as she relaxed on her hotel balcony.
Why so hot?
