The Kardashians take New York! Khloé, Kim and Kourtney Kardashian, and Kylie and Kendall Jenner, hit the concrete jungle during the Sunday, January 10, episode of Keeping Up With the Kardashians, and let's just say they weren't sharing traveling pants. Find out how Kourtney caused drama with her app, plus why Kylie's behavior was (to quote Khloé) "f--ked up."

P.S.: Kim used a body double to try on clothes during her pregnancy, which is a) the most amazing thing ever, and b) caused Kris Jenner to muse, "Is the body double gonna start eating beignets, because she needs a bigger ass." Mother of the year, right here!

Kylie Gets Her Yeezy On

Tyga started yet more drama when he showed up at Kylie's Galore party in NYC and demanded that they hit a different club. The couple's flaky behavior caused Khloé to say, "Kylie, that's f--ked up," while Kim took issue with her youngest sister's attitude in general.

"I've heard from a couple people that you're kinda a diva on set," Kim said. "People love working with me, because I'm so on time, I'm so professional, I get it done."

Kylie ended up killing it during Kanye West's New York Fashion Week show, so looks like she took Kim's advice to heart.

Kardashian Aviation!

For some insane reason, the Kardashians don't own a plane. (The horror! The humanity!) But fear not: They might buy one. "We need to get a family aircraft," Kourtney mused while complaining about the struggle that is walking through an airport. "Tyler Perry offered to sell me his plane."

Totally relatable, right? Meanwhile, Khloé had this to say: "When I fly with Puff, Puff has a whole bedroom. It's a bed." The more you know.

Kourtney: Person Who Is "Not Special"

Did you notice that Kourtney's app didn't launch at the same time that her sisters' did? Turns out she flaked on meetings thanks to that whole "having a baby" thing. "Trying to shift the blame as to why her app is late is delusional," Khloé said. "The truth is, Kourtney dropped the ball."

Kourt tried to explain that her busy schedule put her behind, but Kim wasn't having it. "Everyone in life has a baby and they work, like, 10 jobs," she said. "You're not special. Sorry."

In Which Kris Shades Eddie Murphy

Kris and her boyfriend, Corey Gamble, had an amazing conversation about movies this week, and apparently the Kardashian momager has lots of feelings about Eddie Murphy. "You've never seen Boyz n the Hood. You never seen Friday," Corey said. "You didn't have the right African American man in your life."

Kris tried to counter by reminding Corey that he'd never seen Mary Poppins, and quipped, "Your movies are all, like, they star Eddie Murphy."

Ummm. Eddie Murphy is an icon, Kris Jenner.

Prayer Circle for Jonathan Cheban

Jonathan Cheban is officially over it. Kim's BFF drew the line when she asked him to drop off a urine sample at her doctor's office, calling her "sick" and "crazy." The poor guy ended up taking Kim's urine to the doctor (#blessed), but lost it when Kim made him fetch her a cronut. (Don't worry: She bought him a bowl of soup to make up for it. #DoubleBlessed.)

Update on Kourtney and Scott

Kourtney is ready to let her ex-boyfriend Scott Disick back into her life, but is she ready to get back together? Not so much. While Kourt had Scott take care of the kids while she chilled in NYC, she's not about to become Mrs. Disick. "Not right now," Kourtney told friends. "Like, I don't know if there's a day when Scott would get it together, and be changed, and someone I can depend on, like a partner, but he's none of those things right now. I'm not waiting."

Tell Us: Should Kourtney give Scott another chance?

Keeping Up With the Kardashians airs on E! on Sundays at 9 p.m. EST.
