'You Could Die!' Khloe Kardashian Warned Ex Lamar Weeks Before 'Pot' Scandal

During Sunday's explosive episode of Keeping Up With The Kardashians, Khloe Kardashian told sisters Kim and Kourtney that estranged husband Lamar Odom had taken "five steps backwards" in his recovery.

In the emotional scene, the 32-year-old told her sisters that she even asked Lamar, "You know you could die right now, right?"

But little did Khloe know, Lamar's behavior would grow far worse. Just this weekend, RadarOnline.com caught the disgraced athlete smoking a suspicious cigarette in Providence, R.I., an area known for drugs.

According to RadarOnline.com's eyewitness, who captured exclusive video, Odom was clearly smoking marijuana.

"I looked out my window and couldn't believe it, Lamar Odom was standing nearby getting high," the onlooker told RadarOnline.com. "Anyone within 50 feet of him could smell the pot, he wasn't try to hide it at all."

Sadly, a relapse for Odom wouldn't come as a shock at this point. The 36-year-old, who was found unconscious at Dennis Hof's Love Ranch brothel in Nevada last October following a cocaine overdose, has been caught partying and drinking on multiple occasions in the last five months.

Worst of all, Odom was kicked off a plane jetting to NYC in July, after he drunkenly vomited on himself — and in the aisle — shortly before takeoff.

Does Khloe know about Lamar's latest misstep in his recovery? What will she do when she finds out? Sound off in the comments below.
