The clip cuts out before we hear exactly what Khloe discovered. However, viewers can hear Khloe say the words: “Mum is lying to me.”
The trailer then cuts to Kris trying to defend herself.
“I’m trying to do damage control,” she says.
Meanwhile, Khloe’s brother-in-law, Scott Disick tries to smooth things over.
“She literally thinks you’re going to come for her,” to which Khloe replies: “What? I am [coming for her.]”
While we won’t find out just yet what exactly Kris has done to upset her daughter, fans of KUWTK will know that despite their split, there are no hard feelings between Khloe and Lamar.
The pair married in 2009 after just one month of dating, with Khloe filing for divorce in 2013.
Back in June, Khloe publicly congratulated her ex-husband after his book made it to the New York Times’ best sellers list.
“Look at God!!! Congratulations Lammy! Keep shining,” she penned.
