Kate Moss and Harry Styles regularly hit the party scene together
Posing up a storm as she made her grand entrance, Kate, who stars in the short film, wore a dusky pink polka dot blazer and matching high-waisted flares. Under her black long-sleeved top, Kate donned a leopard print strappy which she unveiled later that evening as she took to the DJ decks.
The supermodel, 40, gave her companion Harry a peck on the cheek and a warm embrace as she sat down for dinner next to him.
The 20-year-old singer was dressed to the nines himself, wearing a black dinner jacket and ruffled white shirt. Harry had styled his long hair into curls and carefully parted them to the side.
Kate Moss showed off her DJ spinning skills later on in the night
Joining Kate and Harry on the star-studded guest list was sports agent Dave Gardner, who is expecting his first child with girlfriend Liv Tyler and spent the night mingling with Harry and his close radio show host friend Nick Grimshaw.
Suki Waterhouse, Poppy Delevingne, Jade Jagger, Noel Gallagher and Mel B also made up the show biz crowd.
Jamaica-born Grace Jones performed on the night, drawing attention wearing a black tutu and loud headdress made of the same material. Burberry star Kate also had the crowd up on their feet as she spun a few hits on the decks alongside DJ Fat Tony.
Upon arrival, guests were served champagne and killer cocktails before sitting down to a lavish dinner, while also being serenaded by a mariachi band.
