Khloe Kardashian Says Kourtney Kept Her From 'Spiraling' Out of Control, Wants Rob to Be 'Happy'

The Kardashian sisters have gone through a lot together during their meteoric rise to fame. But according to Khloe, they were watching each others' backs long before they became reality stars.

As the 31-year-old Kocktails With Khloe host recently shared in a post on her personal website and app, she has her eldest sister, Kourtney, to thank for keeping her from "spiraling" out of control after the death of their father, famed attorney Robert Kardashian.

"After my dad [Robert Kardashian] died in 2003, I was partying all the time, drinking a lot and sleeping in every morning," Khloe shared, as she detailed how the family's clothing store, DASH, got its start.

"At this time, my mom [Kris Jenner] and Kourtney were running their kids store, Smooch, and when the space next door opened up, Kourt got it!" Khloe recounted. "She saw that I was spiraling and wanted to give me responsibility and a reason to wake up in the morning."

"So she told me I was going to help her run her new store," the Strong Looks Better Naked author added. "Kourt, Kim and I were the only employees and really had no idea what we were doing."

According to Khloe, she feels her dad would have been proud of the family’s hard work and perseverance.

"It was really important to my dad that we knew the value of hard work and took responsibility for our own success," Khloe wrote. "Kourt, Kim and I definitely put those values to work when we started DASH. I think my dad would be really proud of us."

Khloe later opened up about her brother, Rob Kardashian, during a livestream on her app, where she addressed his drama-filled relationship with Blac Chyna.

While answering questions and comments from fans on Twitter, Khloe read one fan's message that said, "I just want Rob to be happy and be treated the way he deserves."

"Girl, I agree," she responded. "Whatever makes Rob happy."

It's nice to hear Khloe supports her brother's happiness, because the 28-year-old reality star's recent relationship with Blac Chyna, 27, has reportedly caused a lot of tension within the family -- and Blac Chyna's recent arrest for public intoxication and possession probably didn't help matters.

Check out the video below for a look at why Rob and Blac Chyna's relationship is even more drama-filled (and confusing) than you ever realized.
