Dressed in a white shirt, the 32-year-old was shown from the chest up as she wished her mother congratulations on her new show, Kris.
“I’m sorry I couldn’t be there in person, but I’m just loving life a little bit too much at home right now,” she said. “But I watch you every single day and you are so amazing. You really are born to do this. I just want to say I love you and have an amazing show.”
Guest host Sean “Diddy” Combs set up the clip by pretending it was a preview of his new cable network, Revolt, and as Jenner watched it, she teared up. “That made me cry … Thank you, Kimmy, thank you Sean,” she said, dabbing at her eyes with a towel.
Kardashian looked slimmer in the short video and a source close to the star tells PEOPLE that she has “lost a lot of her baby weight.” Jenner said during the show on Friday that her daughter was “eating really well and working out and nursing.”
