Kris, 57, arrived at the Grove in LA yesterday (10 July) for a chat with Mario, who hosts US celebrity news and entertainment show, Extra.
She kept her outfit simple and chic with a plain black dress and a cute white cardigan, while Mario embraced the sunny season by sporting a bright turquoise polo shirt with a pair of jeans.
Both stars appeared to have had a lot of fun catching up with one another on the Extra set and there didn't seem to be any bad blood or awkwardness between them, apparently proving a rumour they had fallen out briefly during Khloe Kardashian's stint on The X Factor USA wrong.
Khloe starred as Mario's co-host on season two of the popular singing competition, but there was speculation that while she was on the show her momager Kris and Mario didn't always see eye-to-eye.
But Kris and Mario certainly seemed like the best of friends in the Extra interview yesterday!
And given that the Kardashian matriarch is about to become a talk-show host herself, perhaps she could pick up a few tips on how to work the camera from Mario while they're getting along so well?
Khloe, meanwhile, has confirmed that she won't be returning for the next series of The X Factor USA, leaving former Saved By The Bell star Mario as the sole host.
What do you think of Kris' simple style? Let us know below.
