Billie Eilish walked the red carpet at a glamorous Hollywood event on Saturday wearing a duvet, pyjamas and an eye mask.
The singer, 20, opted for a more relaxed look while attending the 11th Annual LACMA Art and Film Gala in Los Angeles with her new boyfriend.
She was pictured wrapped in a monogrammed Gucci duvet alongside 31-year-old singer Jesse Rutherford.
At one point, the couple flung off the luxury blanket to reveal matching silky nightwear by the same high-end fashion brand.
Eilish's ensemble featured an eye mask, lace-trimmed pyjama slip dress and dressing gown, as well as gloves and tights – all bearing the iconic Gucci logo.
She posed alongside Rutherford, who was wearing a pyjama top and trousers in the same silky fabric, as well as a pair of slippers.
It was the couple's red carpet debut together after they reportedly first started dating last month.
While they appeared to – albeit very stylishly – dress down for the evening, others in attendance at the star-studded event pulled out all the stops.
They included Heidi Klum, who opted for a floor-length dress made from purple sequins, which she accessorised with a red clutch, manicure and heels.
The model, 49, appeared to be embracing classic Hollywood glamour after dressing up as a worm for Halloween.
Similarly, Paris Hilton likewise opted for some shimmer at the exclusive party, and posed for the cameras in a cut-out black gown.
Elsewhere model Kendall Jenner confused fans with a 'pause button' addition to her nearly naked sheer dress.
Other attendees included Olivia Wilde, Salma Hayek, Kim Kardashian, Carey Mulligan and Addison Rae.
