Rihanna isn't exactly known for being shy, but it seems she's thrown caution to the wind on the bra front all together.

The musician, 27, flashed her nipple piercing as she ditched her undergarments and stepped out in a sheer black vest.

What's more, Rihanna was hanging out with her younger brother Rorrey Fenty who she took by the arm to walk out of Santa Monica's Giorgio Baldi restaurant.

For modesty, Rihanna robed an oversized leather jacket over her shoulders and left her arms free to swing beneath it.

She carried a quilted handbag underneath to match and never let go of her Ullu brand cow hair snap-on iPhone 6 case.

Rihanna capped off the all-black look with studded block heels that elongated her legs in fitted black jeans.

Rihanna's latest braless display was at Sunday night's BET Awards in LA where she paired a gold shorts suit with no undergarments.

She was there to release a one-minute trailer for B***h Better Have My Money, which sees her take the law into her own hands in an attempt to get paid.

The new song is due for release on July 2, 2015.

The world is hotly awaiting the details on the release of Rihanna's eighth studio album R8, while snippets keep appearing on the internet.

It was reported this week that Rihanna would be taking a backseat after Rihanna's company reportedly set up a new brand, $CHOOL KIlls.

Grazia reports that the brand was registered under the category of 'leather products' and 'clothing products.'

After finding success with a court case against Topshop for using her image on a T-shirt in 2013, Rihanna's creatve director Ciarra Pardo said: 'Rihanna was working hard to identify herself as a serious fashion designer and items such as the T-shirt in issue do not support that goal.'
