On Sunday night's episode of "Keeping Up with the Kardashians," sisters Khloe and Kourtney battled their hearts out over whether or not the former deserved to be paid a massive $25,000 for her interior designing services.

Obviously, Khloe, who was then scouting for a new home post split from Lamar Odom, couldn't decide on which furniture to include into her property.

As such, the 30-year-old reality star sought the help of her older sister Kourtney, who had more experiences with purchasing houses and designing them, according to Hollywood Life.

However, Khloe felt blindsided when Kourtney told her about her expected fee and although she said she agrees that everyone needs to be paid for their services, she couldn't accept the fact that Kourtney, her very own sister, would charge her that much.

Meanwhile, Kris Jenner's mom, MJ Shannon, went to visit the Kardashian clan and opened up about her recent back pains.

In an attempt to help her endure the excruciating pain brought about by osteoporosis, Kris went to consult with a medical marijuana specialist and even purchased a pipe that her mom could use.

Jenner was very excited to tell her mom about her recent purchase, only to find out that Shannon's doctor has already prescribed her with gummy bear-based medical marijuana that she can use to help lessen her back pain and improve her appetite, Bustle reported.

Unfortunately, Kris and her mom tried the drug and got stoned while at the Jenner mansion and Bruce, who was very adamant at saying he's not really a fan of drugs, asked them to stop using it especially with kids in the house.

Once again, everything ends well for the Kardsahian clan and next week's episode will feature Khloe and French Montana's run in with Odom at a bar in Los Angeles.

To add to that, Khloe will once again flare up at her mom Kris.
