In a sneak peek at Sunday's Season 11 finale of "Keeping Up With The Kardashians," the sisters are seen chatting about Khlo's face with friend Jonathan Cheban and point out that the reality star's mug is looking a little different these days.
"Khloe, I was gonna call you and talk to you last night about this," Kim tells the blonde beauty over the phone. "Your whole face has changed. Did you do any filler?"
"No I haven't," Khloe responds.
But Kim and Kourt can't help but push their sister's buttons a little more and make fun of the way she looks when she laughs.
"Khloe, your whole face changes when you laugh. It's like, I stare at you," Kim says.
"No way! But you guys, I think it's 'cause I'm forcing a fake laugh," Khloe tries to explain. "Wait, you noticed it?" Kim asks Kourtney, before adding, "I thought she was on drugs."
Kourtney then whips out a video of Khloe on her phone and shows Kim and Jonathan exactly what she's talking about. "It's like her whole gums and teeth," she laughs.
