A New York based drug dealer, whose claiming to be Lamar Odom's supplier, is saying the NBA superstar spent $50,000 on cocaine in three years.

According to the dealer, who has concealed his identity, just came forward telling RadarOnline that he 'allegedly' witnessed the former Los Angeles Clippers basketball player consumed the illegal drug on as many as 10 occasions since 2010, when Odom visited his hometown of Queens, NY.

Here's what he the John Doe had to say:

"[Lamar] has a huge problem and he has a very addictive personality. It is becoming worse as you can see. He likes to party. He's a pretty nice guy to be honest with you, but he's becoming... his problem seems to be becoming a bigger problem. In my experience, he literally likes cocaine. He is a cocaine guy. He likes to smoke it."

The dealer claim the 33-year-old even freebases cocaine before a game between the L.A Clippers and the New York Knicks at Madison Square Garden on February 10th this year.

"I know it for a fact because I sold him the stuff and saw him smoke it, he spent about $16,000. Quantity wise, it was a little under half a kilo." the dealer adds.

When asked how much Lamar spent over three years, he replied: "Roughly, more than 50 grand...over the time I've known him."

WOW!

Plus, TMZ recently reported that Kris Jenner has hired attorney Robert Shapiro to represent Lamar because of his personal experience with drug addition.

Shapiro's 24-year-old son Brent died of a drug overdose in 2005, and has since been involved with drug addition foundations.
