Kris Jenner pranked her daughters by pretending she had slept with the 25-year-old family chef.

The siblings, along with Kourtney's partner Scott Disick, returned to the house to find their mum's knickers and heard groans coming from her bedroom much to their despair, but when they went into her room and pulled back her bed sheets they saw the pair fully clothed.

Speaking on last night's (14.12.14) episode of 'Kourtney and Khloe Take the Hamptons', Kris joked: "You got punked. We are totally dressed. Who do you think you are? We were onto you guys like stink on s**t."

The playful incident occurred as Kris' daughters were keen to find her a man following her split from husband Bruce Jenner – who she separated from in October 2013 after 23 years of marriage – and Scott joked she could put an advert on classifieds website Craigslist.

But Kourtney, with the help of friend Jonathan Cheban and Khloe, decided to set Kris up with Jordan instead and send the chef up to her room with a glass of wine.

The showbiz matriarch is now thought to be dating Justin Bieber's 33-year-old road manager Corey Gamble after meeting him at designer Riccardo Tisci's 40th birthday party in Ibiza in August.

A source recently said the raven-haired reality star "feels like she's 25 again", adding: "[Corey] constantly tells her how hot, sexy and smart she is."
