, Scott is sitting outside on a porch with Kourtney's sister Kendall Jenner.
The dad-of-three is wearing a green sweatshirt with a gold chain and sunglasses, leaning back in his seat.
He says to Kendall: "I know that we've done some pretty crazy stuff together."
The camera pans to Kendall, sporting bright red long hair, smiling.
"Would you go to space?" he asks Kendall.
Kendall smiles and responds: "I'm happy here."
"You're not landing in Mars and having lunch," Scott jokes.
The trailer was posted to a popular Kardashian online page, titled "Scott Ain't Leaving," where fans sounded off on his upcoming appearance on the Hulu show.
One wrote: "As long as he’s not complaining about [Kourtney and Travis Barker] then I don’t see a problem..."
Another fan commented: "I actually always loved Kendall and Scott together- wouldn’t mind seeing him here and there on the show."
A third viewer, however, wasn't as thrilled: "His storyline is always so constructed. It bores me. He does not contribute to anything on the show other than being the only male 'main character.'"
Scott's appearance comes as fans have raised concerns that Kourtney's husband, Travis Barker, is "controlling" in their relationship.
RED FLAGS?
Viewers claimed they spotted several "red flags" about the rocker's behavior in episodes of the first season of the Hulu show.
One user claimed it's worrying that Travis seems to be involved in all of Kourtney's decisions.
"I don’t see Kourtney making her own decisions very much, at least not in his presence. (He’s always present)," they wrote.
"I probably wouldn’t have noticed if it didn’t seem like he was making several decisions for the both of them. Like, she voiced that she had wanted to look at houses in Malibu, they end up going where he wanted instead.
"Travis couldn’t accompany Kourtney to Saturday Night Live because of his son’s bday in LA – so Kourtney didn’t go. Especially because Scott was going."
The user also drew attention to the couple's incessant PDA, writing: "Maybe I’m also just not used to seeing women being treated like a doll.
"He initiates all the PDA, and no matter how inappropriate it may seem, she complies. And remember how quickly she got off her seat and sat on his lap, per his request? I personally am getting red flags."
Kourtney and Travis tied the knot in an Italian ceremony on May 22 after he popped the question in October.
LAWSUIT DRAMA
Meanwhile, it is unclear if the reality show will touch upon Kourtney's ex Scott's legal troubles.
He and Kim are being sued for $40million for promoting luxury prizes that are allegedly part of a fake lottery scam.
The property mogul, 39, promised fans a chance at winning items like $130,000 cash, first-class tickets to LA and a three-night stay in Beverly Hills.
Sources close to Curated Businesses, the company that organizes the lotteries, told that there have been legitimate winners.
They added that they have the paperwork to prove it.
However, the plaintiffs- people who entered the lotteries but did not win- claim otherwise.
They allege in their lawsuit that Kim, Scott and Curated Businesses organized the competitions on Instagram to allegedly sell their personal information to advertisers.
They claim they have been “invaded by hundreds of advertisers, some of which are soliciting the Plaintiffs with potentially offensive and unwanted content,” according to the lawsuit.
Scott is allegedly the main organizer of the contests and celebrities- like Kim, her sisters Khloe, Kourtney, Kylie Jenner and their mom Kris Jenner- have helped promote them to their millions of fans on Instagram.
The plaintiffs are reportedly asking for $20million each from Kim and Scott.
The U.S. Sun has contacted representatives for Kim, Scott and Curated Businesses but has not heard back yet.
