Kate Moss is a pro at making an entrance, but her arrival at Rimmel London’s 10th anniversary party Thursday night may have been her grandest yet. The supermodel — a longtime face of the brand — descended on southwest London’s Battersea Power Station by helicopter, hopping out to greet guests and dance the night away.

Though sans new husband Jamie Hince, Moss looked happy, radiant and glamorous. Dressed in a black velvet vintage strapless dress, Christian Louboutin shoes and a dash of red lipstick 001 from the new Kate Moss Lasting Finish Lipstick collection, she quickly made her way into the venue as ecstatic fans snapped photos along the way.

Moss was joined at the bash by Solange Knowles, Rimmel’s newest face. The starlet, fresh off of New York Fashion Week, was dressed in a yellow asymmetrical Acne dress and Casadei stilettos, and spent her night entertaining guests from the deejay booth with hits by Whitney Houston and Michael Jackson. “I am a bit overwhelmed,” she admitted to PEOPLE, “and spaced out at the same time!”

Brand ambassador Alejandra Ramos (above) also came out to celebrate, as did Harry Potter‘s Bonnie Wright (there with fiancé Jamie Campbell Bower), dressed in an airy, sleeveless gown by Roksanda Ilincic. “I love makeup but I prefer the natural kind of makeup,” she told PEOPLE. “Unless I am going out, I don’t wear that much, but I always like my lipstick.”

Speaking of, Rimmel unveiled the 15-shade Kate Moss Lasting Finish Lipstick Collection on Thursday during a pre-party press conference with the supermodel. “She’s areal London girl, and we made her kind of a creative contributor to the brand,” Steve Mormoris, senior vice president of global marketing at Coty Beauty, told WWD. “She’s incredibly involved in the creativity in Rimmel, working with the photographers Craig McDean and David Sims, helping them with makeup looks.”

The collection launched last week at Boots in the U.K., and will hit additional stores throughout the country on Sept. 29. In January, the line will debut in the U.S.; lipsticks will sell for $5.17 a piece. Mormoris said the company is considering adding lip glosses and nail polishes to the collection.
