According to US reports, Kris is allegedly being a little mean to Tokyo Toni following the birth - despite them both being in the delivery room together and even posing for an epic Mannequin Challenge video.
"After Dream was born, Kris said some really nasty things to Blac Chyna's mom that really hurt her feelings," a source close to the family is said to have told Radar Online.
"But not only did Kris tell the crew to film Tokyo as little as possible, she also suggested that Tokyo Toni get her hair and make-up redone because it was not up to par with television standards!"
According to the website, Rob and Chyna asked the pair both to leave and Kris later
"Kris was just really stressed out and told Rob and Blac that she did not mean to hurt Tokyo's feelings," the source added.
Following Dream's birth, the 61-year-old momager couldn't stop gushing over the new addition to the Kardashian family.
Alongside one shot of the tot with her grinning father, Kris said she was a "dream come true".
She also previously spoke about how "beautiful" it was to watch the bundle of joy be born.
She said: "I got to watch [the] delivery. It was so beautiful and I'm so excited and happy to have another grandchild! It was one of the most precious moments of my life."
