2:08 PM PT -- 9/1 -- Lamar's manager tells TMZ ... Lamar has zero relationship with celebrity boxing or Damon Feldman. He ended it and he's owed a lot of money.
Fake Drake is missing out on his big celebrity turn with Lamar Odom, and he's blaming real deal Drake for sabotaging his money bag!!!
Fake, Izzy, whatever ... that guy was a recent guest on the WeInMiami podcast, where he got candid about his recent encounter with Drake … who allegedly cold-shouldered Frake and team when approached about the nixed celebrity boxing match with Lamar Odom.

Champagne Papi seemed fine with coexisting with his clone in the past, but lately, he's got no patience for the whole scene. During the podcast, Fake Drake claimed the megastar rapper threatened to pull up to the fight and slap him ... free of charge.
Frizzy also accused Drake of paying off LO to stay out of the ring, but sources involved in the celebrity boxing deal tell TMZ Hip Hop ... Drake cashing out the ex-NBA star is false, and LO simply backed out on his own.
Speaking of fights, one almost broke out during the podcast taping when Sparkling Cider Papi's new opponent, YouTuber M2thaK, promised to remove all signs of Drake … with his fists.
The fight is scheduled to happen in October, and should be worth the price of admission … especially if real Drake shows up to get in a few shots. Hey, we can dream.
