Lamar Odom raps about doing drugs and cheating on wife (VIDEO)

It looks like Lamar Odom's highly-publicized drug problem is only getting worse — at least that's how it looks in this video — shot this month and obtained by TMZ — showing the former NBA player shirtless and incoherently rapping with some other dude.

The totally out-of-it Odom talks about drugs, making money without the NBA, and cheating on his wife Khloe Kardashian in what has to the most damning evidence that this guy needs real help for his drug addiction — and fast.

In the embarrassing "rap" video, Odom mumbles about making money off his fragrance "Unbreakable," and how he smokes drugs to make "the pain go away." He even drops brother-in-law Kanye West's name.

But in the incriminating part — Lamar raps, "And when Khloe's out of town / I still be on the DL." His friend then follows up, "You know what it is / We the QU [Queens] pimps / Ask any of these shorties / We ran through their cribs."

In other words: when his wife is away, Lamar will play.

As TMZ reported, Lamar's currently training hard in Rhode Island, trying to get back in shape for the NBA — but drugs are still obviously a big part of his life.

It's pretty hard to watch this video without cringing.
