She looked stunning as usual, styling her long, honey blonde locks into bouncy waves.

For makeup, she rocked a shimmering bronze smoky eye along with a glossy mauve pink lip.

As seen in a wedding video shot by influencer Tamara Kalinic, the superstar had everyone at Kamani’s afterparty on their feet as she sang We Belong Together.

She also sang some of her slow ballads for the couple’s dance.

Kamani is one of three sons from the billionaire family behind fast fashion brand Boohoo, according to an American newspaper Business insider 2020 report.

His family built their fashion empire from a market stall in Manchester into a multi-billion dollar business.

At the age of 24, he co-founded PrettyLittleThing with his older brother Adam, who has since specialized in real estate and finance.

His company is expected to be worth as much as $2.6 billion next year.
