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

 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.
