In the promo clip for this week's Episode 7, "Special Delivery," of "Keeping Up with the Kardashians," Kourtney Kardashian is very annoyed that Scott Disick plans a Lord Disick party in Las Vegas, Nevada, so close to their baby's delivery date.

In his typical response, Scott assures her everything will be fine. He will have a plane on standby. He will be just 40 minutes away, he says. She tells him that if he's coming to their child's delivery from Vegas, she doesn't want him in the delivery room. She doesn't want him to show up drunk.

Kourtney has every right to be worried. In last week's Episode 6, "Don't Panic," Kris Jenner was fed up with Scott when he brokered a Vegas nightclub appearance for her birthday and showed up wasted and belligerent.

Also in "Special Delivery," Kourtney learns that her due date could be closer than expected, prompting Kim Kardashian and Khloé Kardashian to host a last-minute baby shower.

Despite her sisters' kind gesture, Kourtney gets angry when they start planning a trip out of the country around the time her baby is due. She tells them that even if she does not want them in the delivery room, she wants them in the waiting room, especially since she doesn't know if she can depend on Scott.

Kris gets a shocking call from her personal assistant who says that Kris' private investigator told her someone is demanding money or else they will released hacked closet camera footage. The threat strikes fear in Kris who beefs up security.

Kim and Khloé ask Kris why she has armed guards roaming the property. Kris tells them she needs protection because her security has been threatened. When she says the security guards gave her bullets for a gun Bruce gave her, Khloé thinks she needs to calm down, and not load or carry the gun. She doesn't want Kris to accidentally shoot anyone.
