Father of the year? Scott Disick just couldn't resist Sin City's siren call during this week's Keeping Up With the Kardashians, and Kourtney Kardashian lost it when he planned an event around her due date. The reality star, pregnant with her and Disick's third child together, was concerned that Scott wouldn't make it to the delivery room on time, or — even worse — that he'd show up drunk!

Bye-Bye Baby

There's no doubt that Scott adores his family, but he wasn't exactly enthusiastic about baby number three. "I truly hope that he can get it together because the baby is due at the end of the month and I really need his support," Kourtney told cameras. Too bad The Lord wasn't in a supportive mood — when Kourt tried to show him baby clothes, he stormed off and said "I've seen nine thousand child's outfits, I cant be excited about everything." #LordFail.

Delivery Room Drama

Kourtney decided not to have the Kardashian clan in the delivery room with her, but she was worried Scott wouldn't be around when push came to shove. Scott's shocking response to her concerns? "I'll probably be there," he said. "50-50." Kourtney was clearly upset at her man's casual attitude, saying "It's really hurtful because I want to be able to depend on him, and that he's gonna be home and excited to be there."

Gone Daddy Gone

Scott planned a trip to Sin City right around Kourtney's due date, and his timing couldn't have been worse. "Last night Scott mentioned that he booked another Vegas appearance, which is the last thing he should be doing," the mom-to-be said. "It's really frustrating, because I was hoping he'd step up and really be here for me. It just doesn't seem like that's happening right now."

Scott said he could fly home for his baby mama's delivery, but she wasn't having it. "If I did go into labor while Scott is in Las Vegas, there's not even a one percent chance that I would tell him," Kourtney said. "I don't want him drunk in the delivery room." Get it together, Daddy Disick!

Lord Gone Wild

What happens in Vegas definitely doesn't stay in Vegas when your last name is Kardashian. Thanks to Scott drunk-texting her siblings, Kourtney ended up finding out about his crazy behavior and wouldn't let him stay at the house — which meant he had to crash at Khloe's. "I don't know what Scott's doing and I really cannot depend on him right now," Kourtney said.

Scott ended up being by Kourtney's side when she gave birth to their son, Reign Aston Disick, on Dec. 14, 2014, but judging from next week's preview this new mom is still throwing major shade at her unreliable partner.
