Olivia Rodrigo & BLACKPINK's Rosé Pose Together in 2021 Met Gala Selfie

Olivia Rodrigo and BLACKPINK's Rosé cherished their time at the 2021 Met Gala on Monday with a selfie from the night.

The "Good 4 U" hitmaker shared a selfie of the two alongside actress Talia Ryder, who starred in Rodrigo's "Deja Vu" music video, via Instagram Story on Tuesday (Sept. 14).

Both pop stars (and Ryder) wore Yves Saint Laurent for their first-ever Met Gala, and it was a watershed moment for K-pop: Rosé and CL became the first-ever K-pop idols to walk during fashion's biggest night. The 24-year-old K-pop singer posted a picture of herself next to Anthony Vaccarello, YSL's creative director, and Rodrigo commented underneath, "beauty queen!!!!!"

And the two have more in common: At one point this year, Rodrigo and Rosé both boasted having the biggest song in the world, when the former's debut single "Drivers License" was No. 1 on both the Billboard Global 200 and Billboard Global Excl. U.S. charts, where it ruled for eight weeks, and the latter's debut single "On he Ground" topped both of Billboard's global charts for two weeks.
