"She's [being] shady in general about this show. Like Kim and I call her [and ask], 'What are you doing?' And she [whispers] 'We're filming' and she doesn't tell us anything that is going on," Kourtney told Jimmy Kimmel during a Thursday night appearance on his Jimmy Kimmel Live late-night show.
"Like what goes on in the Odom household, we don't know. Because it's not like we hang out there all the time. We're usually at my mom's house or, I don't know.
According to Kourtney, Khloe's secrecy about the show has been a shared point of frustration for her and her sister Kim Kardashian, whom she co-stars with in Kourtney and Kim Take New York, the new Keeping Up with the Kardashians spinoff which premiered on E! on Sunday night.
"Kim and I are like, 'She's so shady!' We were talking about this on the plane to New York! 'What a shady girl!'" Kourtney told Kimmel.
"I don't know what Khloe and Lamar's show is called!"
According to E!, Khloe and Lamar's new spinoff -- which the network formally announced earlier this month and has given the working title of Khloe and Lamar -- will follow Khloe and her NBA basketball star husband in their daily life and chronicle their life together as a married couple.
In addition to showing how the 26-year-old Kardashian has taken on the roles of a wife and a stepmother to Destiny and Lamar Jr., Odom's two children from a previous marriage, it will also follow Odom's life as a member of the Lakers NBA basketball team both in Los Angeles and on the road.
