KRIS Jenner was caught on camera barking at noisy crew to "shut up" while filming an interview about Kylie Cosmetics.
The diva momager can be seen strutting into her daughter Kylie Jenner's make-up HQ before snapping at staff members.
Wearing a crisp white trouser suit and dark sunglasses, Kris could be mistaken for iconic movie character Miranda Preistly in The Devil Wears Prada.
In the tongue-in-cheek opener for the Inside Kylie Cosmetics: Part 2 video, she pauses to look at a giant, framed photo of herself on the wall.
The fiercely driven reality star, 65, then slips down her shades nods approvingly at the picture, which shows her displaying the middle digit.
Kris slowly makes her way to a film set, before sitting down in a white leather chair and removing her sunglasses.
KRIS GOES ALL OUT
As the cameras roll, she is asked: "So, who are you?"
Without skipping a beat, Kris replies: "Kris F***ing Jenner."
Then, as background noise disturbs filming, she yells: "Quiet on the set. Shut up!"
As the room falls silent, Kris smooths down her dark hair and says, "just kidding," before winking at the camera.
The new video is the second part of a mini documentary about Kylie's multi-million dollar brand Kylie Cosmetics.
During the 10-minute film, Kylie speaks about how much her mom influences her when it comes to business - but not creativity.
ALL ABOUT MOM
The 23-year-old admits: "Kris Jenner...is a very smart woman. But she as far as creative, we don't really align. She will come with some really fire ideas, like once or twice a year.
"Every other idea is amazing, but when it comes to like colour, or name or collection, she's got like two good ideas a year."
Kris happily admits that her daughter is right, adding: "I learned very early that I wasn't the creative person. I'm gonna stay behind my desk."
The Kylie Cosmetic staff, however, do admit she is a tough taskmaster.
"A lot of the business stuff, Kris really handles," Jen Cohan, Chief Brand Officer, says. "If you wake up, Kris Jenner's probably texted you before you were even awake."

Megan Mildrew, Chief Commercial Officier, adds: "She's up, she's had a coffee, she's on the treadmill and she's having board calls. She's like ready to go."
