Rihanna left fans hot under the collar at the weekend.

The singer slipped on a seriously sexy swimsuit for a dip in Brazil on Saturday and uploaded a number of shots of herself to Instagram.

In the photos, the Bajun beauty, 25, confidently shows off her pert posterior and boobs as she stands in water.

Rihanna – who added to her racy look with red lips and wild curls – had her body praised by countless admirers.

‘Perfection from top to toe @badgalriri ♡,‘ one fan wrote next to one Ri-Ri from behind.

Another added: ‘That ass.’
