On the next Keeping Up With the Kardashians, viewers will get a closer look at Kris Jenner's epic 60th birthday bash, and ET has a sneak peek!
In the clip, Kris tries on dresses for the Great Gatsby-themed soiree that took place at The Lot in West Hollywood last November, while Kim Kardashian and BFF Jonathan Cheban help her choose a look while privately discussing who the second performer should be for the party.
"I have stuff in here older than you are," Kris tells Jonathan, while rummaging through her closet.
"Is there a picture of you actually wearing this?" Jonathan asks, gesturing to a red gown. "Were the pictures black and white back then?"
Later, putting all jokes aside, Jonathan praises Kris for her youthful appearance, saying, "I don't even believe that you're 60!"
While the momager slips in and out of several lavish gowns, Kim and Jonathan get some planning done.
"We need another performer," Jonathan whispers to Kim. "You guys cannot just have one person."
"That's what Kanye keeps saying, but who?" Kim says.
"Him in a minute!" Jonathan answers. "I think Kanye's going to have to step in and do it."
Kanye did in fact perform at Kris' birthday bash, serenading his mother-in-law with the "Happy Birthday" song.
Charlie Wilson also sang at the event in front of a room full of famous guests including Lisa Rinna and Harry Hamlin; Chrissy Teigen and John Legend; Melanie Griffith and daughter Stella Banderas, and all of Kris' children.
Keeping Up With the Kardashians airs Sundays at 9 p.m. ET/PT on E!.
