Kris Jenner is all about helping Rob Kardashian with his new home.

The reality star enlists celebrity interior designer Faye Resnick to help decorate the 29-year-old's new pad in a clip from this week's Keeping Up With the Kardashians.

"I am so excited to get his house all set up and help him get settled in," Kris shares.

"We wanna see Rob's new place and make him happy," Kim Kardashian West adds of Kris' willingness to offer up assistance. "And I know that my mom's really happy. He hasn't been like this in so long."

But not everyone is so happy about all the help Kris has been giving Rob. In another new clip, Khloe Kardashian comes to blows with the family matriarch after learning that she's paying for her son's $2.3 million home.

"You are one of the biggest liars," Khloe says to Kris. "I'm just allergic to bullsh*t."

"I would have such deep fights in my family because I was 'enabling' Rob by letting him live with me," she explains. "And then the one person who yelled at me the most, my mom, now she's helping Rob? I just find it mind-blowing."

Meanwhile, house-helping drama aside, Kris has a lot to look forward to with Rob's engagement to Blac Chyna and the couple's baby on the way!
