And even Lizzo couldn't hide her awe when she spotted the reality TV star on the red carpet.
A TikTok posted by iHeartRadio captured the moment Lizzo watched Kardashian make her arrival at the Metropolitan Museum of Art in New York City on Monday night.
Lizzo was playing a song on her flute when she caught Kardashian's entrance.
The "About Damn Time" singer dropped her instrument to point Kardashian out to reporters.

"It's Kim Kardashian y'all, fuck!" Lizzo exclaimed. "She look good as fuck too."
Kardashian was the last star to arrive at the Met Gala, stealing the spotlight as she walked out in the iconic gown that Monroe wore to sing "Happy Birthday" to President John F. Kennedy nearly 60 years ago.
Kardashian first tried on a replica of the Bob Mackie dress — which sold at an auction for $4.8 million in 2016 and is now at Ripley's Believe It or Not Museum in Orlando, Florida — and it fit perfectly, according to Vogue.
But when she tried on the real dress three weeks before the Met Gala, it didn't fit. So she completely cut carbs and sugar from her diet.

"It was like a role, I was determined to fit it," she told La La Anthony during Vogue's red-carpet livestream on Monday.
Kardashian — who was at the Met Gala with all five of her sisters for the first time ever — also revealed that she spent 14 hours getting her hair bleached blonde on Sunday to match Monroe's iconic locks.
A representative for Browne told Insider that Lizzo's ensemble included a corset dress in black silk moiré with a dropped skirt, and an oversized chesterfield coat in black duchess satin. The coat was adorned with silk satin stitch embroidery.

During her interview with Variety, Lizzo also revealed that the "rare flute" she brought to the event cost $55,000. She performed a small showcase on the Met Gala's red, white, and blue carpet.
