Eilish, Lil Nas X -- and yes, Rihanna -- dazzle at Met Gala

Billie Eilish went full glam in a huge peach ball gown at the pandemic-delayed Met Gala on Monday night, while fellow host of the evening Amanda Gorman was breathtaking in cobalt blue custom Vera Wang with a diamond laurel wreath in her hair.

Rihanna, ever the Met Gala queen, showed up late in a huge black Balenciaga look and hat accompanied by A$ap Rocky in a multicolored quilted coat from ERL. She wore over 267 carats of Bulgari diamonds, including two choker necklaces. Co-host Timothee Chalamet raced onto Fifth Avenue to take selfies with fans before walking up the steps of the Metropolitan Museum of Art for his entrance after a marching band and gymnast Nia Dennis kicked off the long-awaited evening. Last year's gala was canceled due to the pandemic. This year's official theme of the fundraiser for the museum's Costume Institute was "American Independence," leaving plenty of room for interpretation. Just ask Lil Nas X, who did a Lady Gaga-esque strip tease on the carpet in gold Versace, from cape to armor to embellished jumpsuit. Eilish, the belle of the ball, wore Oscar de la Renta. She told Vogue: "It was time for this. I feel like I've grown so much over the last few years."
