The 31-year-old Keeping Up With the Kardashians star made her comments in an exclusive interview with E! News' Catt Sadler, ahead of the Jan. 20 premiere of her new FYI Network talk show, Kocktails with Khloe. Khloe said Kourtney, 36, is currently not looking for a new man.
"I've been like, 'Do you want to go on a date? Like, what do you want?'" she told Sadler. "She's not thinking about that yet. You know, she's so all about her kids, so all about, you know, 'Let's get also Scott healthy and in a good spot.'"
Kourtney's ex, who has battled substance abuse over the years and has been to rehab before, began new treatment program this past summer.
Khloe also said she thinks it takes time for moms to stop believing they would have a hard time finding someone because they have children.
"Everybody, Kourtney, would want to bone you," she said. "So stop."
Kourtney and Scott, 32, broke up over the Fourth of July holiday last year and have since reunited several times, often with their children. They are parents to sons Mason Disick, 6, and Reign Disick, 1, and daughter Penelope Disick, 3.
Scott has recently been spotted out with another woman, Swedish model Lina Sandberg. The two recently dined at a Beverly Hills restaurant Kourtney has often frequented, sometimes with their kids.
In her interview with E! News, Khloe also addressed recent rumors involving Kourtney...and Justin Bieber, a friend of the family.
She and the 21-year-old singer had sparked romance speculation after they were spotted out together on several occasions. When asked in a radio interview, airing this week, if anything was there, the singer said, "Nah, we'll leave it at that."
"Justin has been a friend of the family's for years and years," Khloe told Sadler. "They go to the same church."
