She officially became a billionaire earlier this month after the success of her Fenty Beauty brand.

And Rihanna proudly showcased the results of her vast fortune as she stepped out in a blush nightgown for dinner in Santa Monica on Friday night.

The Work hitmaker, 33, left little to the imagination as she went braless in the thigh-skimming slip dress as she left Giorgio Baldi restaurant with her niece Majesty, 7.

Rihanna put on a leggy display as she left the Italian restaurant in silver wrap tie stilettos which featured a perspex heel.

The recent billionaire loaded up on the bling for the outing and accesorised the bedazzled slip dress with a glittering beaded choker.

She also added a large diamond pendant necklace, matching hoop earrings and an emerald and gold bracelet to the look.

Rihanna toted a metallic clutch bag for the outing and accentuated her natural beauty with a bold red lip and shimmering highlighter on her cheeks.

Rihanna swept her long raven tresses up into a high ponytail for the meal in Santa Monica and braided the front sections while leaving one plait loose.

The star was accompanied on her Friday night on the town by her seven-year-old niece Majesty who was dressed in a monochrome sweater vest.

She paired the knitwear with a pair of light denim jeans and some tie-dye patterned Crocs as she sweetly held her auntie’s hand while they left the restaurant.
