Lamar Odom tests negative for drugs

So after weeks of rumors about Lamar Odom being hooked on crack cocaine, he recently tested negative for drugs in both blood and urine tests. So which Kardashian has been feeding the press news of his supposed drug addiction? This doesn't make sense at all. See the TMZ report below...

Our sources say on Tuesday Lamar underwent blood and urine tests for drugs, and he tested negative for drugs. This is consistent with what other sources have told us about his time with the Kardashians on Tuesday. We're told he was lucid and showed no signs of being under the influence of drugs. 

We're told Lamar has had private conversations with execs from several teams who have expressed interest in him, provided he could show he was clean ... and the purpose of the trip is to meet with them and possibly strike a deal.
