Khloe Kardashian addresses her marital issues with Lamar Odom as well as his alleged drug addiction issues on her family’s E! reality show Keeping Up with the Kardashians during the new episode on Sunday.

Fans weren’t sure if she would address the touchy subject on the show, which she has been reportedly hiding for two years, but she alludes to it in a new teaser.

“There are, you know, some things, that not everybody knows. And me and Lamar are the only two people that do need to know that,” she says, Entertainmentwise reports.

When confronted by her sister Kim Kardashian, Khloe says "I'm not ready to continue with fertility treatments” but wouldn’t tell her why. She’s also seen secretly on the phone with her husband and asking him if he’s OK.

Kim tells her sister "You are obviously trying to avoid something and you're afraid of it,” to which Khloe replies, "Why are you so pushy?"

The couple recently spent their 4-year wedding anniversary apart and Khloe has since dropped the Odom from both Instagram and Twitter. However, she continues to wear her wedding ring and is reportedly determined to get through this rough patch.
