Beauty in paradise! Rihanna bares her pert derriere in tiny bikini as she shares MORE exotic snaps from her Hawaiian vacation

She may be in Hawaii to attend a wedding but Rihanna, and not the bride-to-be, is definitely the one getting all of the attention.

The sexy singer posted another round of bikini snaps from the exotic locale on her Instagram page Saturday showing off her fabulous body.

The 27-year-old captioned the shots with '#davis420wedding,' a reference to the marriage scheduled for Monday of her longtime assistant Jennifer Rosales to Aaron Davis.

 n the photos, Rihanna rocks a teeny weeny patterned bikini and poses in the pool, lying on a sun lounger and taking photos on her phone.

In one shot, she's lying on her front with her red curls cascading down her back and showing off her amble booty and long tanned legs. She captions the snap with one word: 'Ginger'.

In another picture, she poses provocatively in the water, turned toward the camera wearing a giant pair of range framed sunglasses and with the fingers of one hand pressed to her red painted lips.

In a third image which she captions with 'girlz on film', she's seen sitting on a sun lounger holding up her phone in one hand as if trying to take a picture.

Displaying some impressive cleavage and her tattoos, the stunner looks relaxed as she enjoys the shade of a palm tree. 

Saturday's photos are the latest in a series the star has shared from her Hawaii vacation during the past few days.

Brides.com reported back in March that the R&B singer had attended her longtime friend's bridal shower held at an upscale beachside location.

Now the big day is near and Rihanna obviously intends to make the most of the time with her friend before she ties the knot, as well as recovering from last weekend's excursion to the Coachella music festival with Rosales and other pals that caused quite a stir.

Chris Brown's ex was seen in a video posted to Instagram and then quickly deleted, that showed her sitting at a table with what looked like a slim white tube in her hands as her pals danced around her.

After the camera cuts to her friends, it then pans back to Rihanna holding her nose for several seconds.

She later hit back on social media insisting that the white tube was actually a joint.
