Khloe Kardashian is done keeping up with her ex-husband Lamar Odom‘s secrets.

In fact, the reality star had no problem confronting him over his past substance abuse during the couple’s first face-to-face meeting in nine years, bluntly asking Los Angeles Lakers alum “why on earth” would he ever return to drugs after his 2015 overdose.

According to Khloe, she found out Lamar started doing drugs again in May 2016. At the time, Lamar—who Khloe broke up with two years prior—was staying at her home and was finishing up his recovery from his near-fatal incident, during which he suffered six heart attacks and 12 strokes while in a three-day coma.

“I was there through it all,” Khloe told her ex on the Feb. 13 episode of The Kardashians, noting that she had to change his diapers and help him learn how to walk again amid his recovery. “I remember everything.”

After Lamar argued that he couldn’t really tell if he was “even thinking” when he broke his sobriety, Khloe contended that he “had enough awareness to get a burner phone to call a drug dealer” behind her back.
