Legends only. Sure, there were all those fashions worn on the red carpet at the 2021 Met Gala, which took place on Monday (September 13), but there's another moment that has us talking... still.

And that moment is the fact that The Real Housewives of Beverly Hills' Kathy Hilton attended a Met Gala after party hosted by Rihanna. While there, you can bet that the two fashionistas got in some time to hang out with one another.

"Fun night in NYC at @badgalriri’s party!" Kathy, who was also spotted at New York Fashion Week, captioned a set of photos and videos from the bash held in NYC. She added in the comments: "Yes we had a drink with her."

Kathy sadly didn't spill any more details about the night but did share this awesome photo.

Bravo's Project Runway's Christian Siriano attended the Rihanna-hosted party as well. And he joked to Page Six, “I want to dance. Where’s RiRi?" (We assume she was with Kathy perhaps having a bottoms up moment.)

Christian also posted about attending Rihanna's party to his Instagram Stories where he was spotted with Lili Reinhart, whom he dressed for the event.

Kathy is the latest in the Real Housewives orbit to hang out with Rihanna at the Met Gala. Leah McSweeney previously opened up about her own memorable encounter with the superstar at the lavish event several years ago.

"One of my most memorable New York City nights had to have been when I went to a Met Gala after party," she said. "I got introduced to Rihanna and she thought she knew me already — and she gave me a huge hug and was like, 'I know you!' and I was like, 'Actually, you don't know me. But, you wear my clothing line. You wear my brand, and thank you for that.'"

The Real Housewives of New York City cast member added, "She was like, 'You're the girl that does that brand?' and I was like, 'Yeah!' She was like, 'Oh my god, come here!' [She] gave me a huge hug again and she was just so cool. That's definitely one of my best New York nights."

There is even a photo of the encounter, which has also become legendary. "Mom I made it! Thank you @shermyworld for this epic night at the MET after party a few years ago when I got to finally meet and have a special moment with @badgalriri which ended up in her book," Leah previously wrote on Instagram. "I’m gassed!!!"
