Revealed: Rihanna wore a $1.8 MILLION diamond belly chain to Beyonce and Jay-Z’s Oscars after-party

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

Page Six reported the price of the bespoke necklace Rihanna wore to Beyonce and Jay-Z’s after-party at the Chateau Marmont – but those weren’t the only diamonds she wore.

In all, the 35-year-old Diamonds singer wore over 250 carats of Bayco stones worth $2.67 million, the outlet reports.

Above the belly chain, Rihanna also wore a three-row diamond necklace set with approximately 96 carats of pink gemstones, a pair of stunning flower-shaped earrings set with approximately 12 carats of diamonds, and a dazzling ring.

It was the fourth outfit Rihanna wore that night.

For her after-party appearance, Rihanna rocked a metallic silver coordinate – designed especially for her by Valentino creative director Pierpaolo Piccioli – and showcased a sequined bandeau top and matching pants.

She completed the look with a dramatic pink coat along with a chunky diamond choker and matching earrings.

The Rudeboy singer accentuated her face with bright makeup and let her brunette tresses fall down her shoulders.

Meanwhile, A$AP Rocky, with whom the beauty is expecting a second child, opted for a sleek black tuxedo when he brought her to the party.

The couple got out of a big black SUV and drove to the iconic Hollywood Hotel.

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

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

Arriving on the red carpet, she flaunted her baby bump in a dominatrix-style sheer leather look.

The mom-to-be paired a flowing black skirt with a long train, a sheer bodysuit and a leather bra.

She first announced she was expecting her second child with boyfriend A$AP Rocky while appearing on a Super Bowl halftime show last month.

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

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