Rihanna shows off bum as she flashes underwear in public months after saying she regrets showing nudity in the past (video)

Rihanna took to Instagram to show off her bum in a cheeky new video.

The Diamonds hitmaker, 36, rocked a stylish schoolgirl-inspired outfit and playfully flashed her black underwear at one point.

Peeking out from underneath her loosely buttoned shirt was a black lace bra from her Savage X Fenty lingerie brand. 

The mom-of-two also joked that she’s given up on trying to have a six pack this summer.

“Since I clearly won’t be achieving my six pack til next summer, I switched my summer goal to matching my shoes to my panties!” she captioned the post. 

This comes just months after she said she regrets showing nudity as a young woman.

The mother of two said whenever she looks back at her bikini fashion, she wonders if she “really did that”. She said being a mother has influenced her new fashion sense.
