Scott Disick is ready to prove he's not the man everyone makes him out to be.
In a sneak peek clip from the newest episode of Keeping Up With the Kardashians airing Sunday, Kim and Khloe Kardashian discover Scott has entered a 30-day rehab program.

The clip then jumps to a solo interview with Kim, who explains that she randomly ran into Scott as she was sitting in her mom, Kris Jenner's, kitchen. The two talked for about 30 minutes and, according to Kim, he seemed "normal."
"Have you heard that Scott has gone to rehab?" Kim asks Khloe, whose shocked expression proves she had no idea.
"I had no idea that he was dropping by," she says. "He wants to really get it together and wants to go to rehab for a really long time and I think that it all sounds amazing but I just hope that he sticks with it."
Kim tells Khloe that Scott claimed he was eight days' sober during their chat, saying, "I just want to really get it together this time for my kids. It was really positive."

Khloe chimes in, saying she hopes Scott will stay and go through with the full treatment.
"I am surprised that Scott has gone to rehab just because I feel like I was just hearing he was on the streets partying," Khloe explains.
The two then chat about how their oldest sister Kourtney -- Scott's on-again, off-again girlfriend -- is feeling about the situation.
"She's been really distant from him and wants to keep her distance," Kim reveals. "So I think she’ll be proud of him and hoping for the best."
The episode was filmed last November when Lord Disick, 32, entered a Malibu, California, treatment facility. Since then, Kourtney has seemingly moved on from her ex-beau for good, confirming that the two were not together during an appearance on The Ellen DeGeneres Show earlier this month.

Scott, however, is staying close to the famous family for the sake of he and Kourtney's three kids -- Mason, 6, Penelope, 3 and Reign, 1. As ET previously reported, Scott recently purchased a $5.96 million bachelor pad right around the corner from where Kim and her husband, Kanye West, reside, and just a few blocks away from Kris' home.
Scott is also appearing on this week's episode of Khloe's new show, Kocktails With Khloe, and in a preview video, he opens up about his life in the spotlight.
"I'd really rather never be in a tabloid again," he admits. "A lot of people think I only care about money and cars. It's more just about insecurities, and how much I care about my friends, and my family."
As we patiently wait for Keeping Up With the Kardashians to air Sunday at 9 p.m. ET/PT on E!, hear more from Scott in the video below.
