The songstress shared plenty of photos on her Instagram account, which showed her posing seductively by the pool, soaking up the sun rays and even having a drink underwater!
Rihanna, 25, who is still on her 'Diamonds World Tour', was captured enjoying some downtime in Dominican Republic.
Posing in a skimpy multi-coloured pink and orange bikini, the 'Stay' singer wore black aviator sunglasses as she rested on a sun lounger in the pool.
Keeping accessories to a minimum, Rihanna bared large gold hoop earrings and several silver rings on her fingers.
Her chest tattoo, which is a design of Egyptian goddess Isis spreading her wings and kneeling, was also visible.
Clearly enjoying the Caribbean climate, Rihanna captioned one photo: "With love from #DR."
Last night (29 October), Rihanna performed a concert in Puerto Rico, and the crowds clearly left her impressed.
Taking to Twitter, she said: "#PuertoRico I'm truly blown away by you! Thank you so much for giving me one of the best nights on tour!! #dwt."
Rihanna's mammoth world tour will come to a close on 15 November, when she returns to the US for her final show in New Orleans.
