On Sunday’s episode of Keeping Up With the Kardashians, the family proved that they don’t have to be in Hollywood to have a little drama.

From Kylie Jenner’s diva behavior to Kim Kardashian’s (rude) comment over the delay of Kourtney’s app, the sisters’ visit to New York City was surely memorable.

Despite the fact she was busy giving birth to her third child, Reign, and went through a very public break-up with longtime boyfriend Scott Disick, the pair gave their big sister a hard time about not launching her app on time.

“Everyone in life has a baby and they work, like, 10 jobs," Kim explained. "You're not special. Sorry."

Khloe, who always has Kourtney’s back, didn’t disagree. "Trying to shift the blame as to why her app is late is delusional," she added.

There seems to be no reconciliation in the near future for Kourtney and Scott, who called it quits over the summer.

"I don't know if there's a day when Scott would get it together and be changed and someone I can depend on as a partner, but he's just none of those things right now," the mom of three told Khloe.

"I'm not waiting [for him]," she added. "I love Scott, but I've gotten to a place where I'm just living life again and I need to separate myself, because every time I carry his problems on my shoulders -- I physically can't keep doing it.”

"Scott really needs to help himself and I need to focus on myself."

Meanwhile, Kylie’s Galore launch party was cut short when Tyga showed up and basically demanded that they take the event elsewhere.

"Kylie, that's f**ked up," Khloe told her youngest sister, as she dipped out of HER party, although she promised she’d meet up with her sisters later.

Khloe wasn’t the only one annoyed by the 18-year-old reality star’s attitude. Kim was a bit nervous about her sister’s “diva” behavior, considering she was about to walk in her husband Kanye West’s runway show at New York Fashion Week.

No worries though! Everything went off without a stitch and Kylie killed it on the runway.
