Dennis Rodman Makes It RAIN in Vegas -- Who's Broke NOW?!?! [VIDEO]

If Dennis Rodman's really broke, he hasn't gotten the memo -- because earlier this month in Vegas, he LITTERED the floor of some clothing shop with cash ... and the rainstorm was all caught on tape!!!

Sources tell TMZ, Rodman had just wrapped a hosting gig at Tabu nightclub -- and a few hours later, he hit up a clothing store at the MGM Grand with his entourage.

Before long, The Worm was flinging stacks of singles into the air ... lining the floor of the entire store with cash. We're told he also spent a couple thousand on new threads while he was there.
