Rihanna took Oscars style to a whole new level as she celebrated the night in a diamond belly chain reportedly valued $1.8 million. 

Page Six reported the price of the custom chain Rihanna wore to Beyonce and Jay-Z’s afterparty at the Chateau Marmont – but those weren’t the only diamonds she was wearing either.

In total, the Diamonds singer, 35, was wearing over 250 carats of Bayco stones worth $2.67 million, the outlet reports.

On top of the belly chain, Rihanna was also wearing a three-row diamond necklace containing around 96 carats of rose-hued gems, a pair of stunning floral shaped earrings containing around 12 carats of diamonds, and a dazzling ring.

It was the fourth outfit Rihanna wore that evening.

For her appearance at the afterparty, Rihanna rocked a silver metallic co-ord – designed especially for her by Valentino creative director Pierpaolo Piccioli – and featured a sequinned bandeau top and matching trousers.

She completed the look with a dramatic pink coat as well as a thick diamond choker and matching earrings.

The Rudeboy singer accentuated her feature with radiant make-up and let her brunette tresses tumble past her shoulders.

Meanwhile A$AP Rocky, with whom the beauty is expecting a second child, opted for a suave black tuxedo as he arrived to the bash with her.

The couple emerged from a large black SUV and headed into the iconic Hollywood hotel.

Earlier in the evening Rihanna was draped in diamonds as she rocked a black bra underneath a bejewelled sheer top as she performed her hit Lift Me Up during the star-studded ceremony.

Rihanna then donned a green silk skirt, shawl, matching gloves, strappy heels and statement earrings.

When arriving on the red carpet, she put her baby bump on full display in a dominatrix-style sheer leather look.

The expecting mother teamed a flowing black skirt with a long train, see-through body suit, and leather bra.

She first revealed she was expecting her second child with boyfriend A$AP Rocky when she performed a the Super Bowl halftime show last month.

After she took to the stage at the football game, many were quick to notice that she had a baby bump, and her publicist confirmed that her second child was on the way soon after.

The Fenty Beauty founder is already the mother to her 10-month-old baby boy, whose name has not been shared with the public.
