Way before Kimmy K and her sisters came on the scene, it was the gorgeous J.Lo who was Queen of the Booty – but she doesn't seem to mind passing her crown on!
Jen told USA Today: "She tells me all the time that I'm her idol and stories about when she used to follow me when my first album was out, and stuff like that.
"She's a sweet girl, and it's very flattering to meet any of your fans! She's always been very open about that and it's very flattering to me. She's a sweetheart."
The glam stars were pictured hanging out together at the Met Ball earlier this month, where Kim shared an image to Instagram of them sashaying down a corridor together.
Her caption read: "With my idol."
It seems even celebrities can get a bit starstruck!
Kim, meanwhile, has been over in Brazil the past couple of days launching her C&A fashion collection and looking bootylicious in a slinky black dress.
Her trip to Sao Paolo did mean, however, that she missed US Mother's Day on Sunday - but husband Kanye West made sure she wasn't forgotten by having hundreds of white roses sent to her hotel room. Aww!
Next up for Kimye is their first wedding anniversary later this month, while their daughter North will celebrate her second birthday in June.
