Kardashian pulled off en epic April Fools' Day prank in a series of Snapchat videos as she claims to have found her ex and the father of her three children getting cozy in bed with Jenner.

The video clips first show the 'Keeping Up with the Kardashians' star looking for Jenner around the house as she asks Kylie if she's seen her sister around.

"Hey Kyles, have you seen Kenny?" Kardashian asks in the video. Kylie responds, "I literally just saw her go over there," pointing down the hallway.

Kardashian then wanders around the house in search of Kendall, checking several rooms in the house before coming across a bedroom door. The 36-year-old enters the room, camera in hand, to find Kendall in bed. "Wait, who is she in here with?" Kourtney asks, walking over to find her cuddling in bed with Disick. "What the..." she yells before the clip ends.

The next Snapchat story shows Kardashian chasing her ex into the driveway as she says, "You're so sick, you're so inappropriate, like, what is wrong with you?"

Kardashian and Disick split up last summer after a nine-year-relationship. However, the two have been spending time together for the sake of their three children; sons Mason, 6, and Reign, 1, and 3-year-old daughter Penelope.

This is not the first time the two have joked around on Snapchat together. Earlier this week, the pair announced that they were getting back together as a joke on Snapchat.

"Hey, so, we wanted you guys to hear it first. We are getting back together," Disick said in the video as he leans in to plant a kiss on Kardashian's head, as she laughs, saying "no."
