Charlie Sheen Detroit Live Show with LA Rapper Simon Rex/Dirt Nasty Turns into Total Disaster

Charlie Sheen's "musical director" Simon Rex and Charlie Sheen stare dumbfounded at a Detroit crowd that wants its money back (actually, this is from Scary Movie 3)

We're recieving several reports from multiple sources that the debut of Charlie Sheen's incomprehensible victory tour of live shows around America has turned into a total disaster.

Dissatisfied customers are heckling and demanding refunds, and Sheen's attempt to entertain the crowd with music by bringing LA rapper/TV personality Simon Rex only made things worse.

Hip-hop writer Jeff Weiss profiled Simon Rex last December for LA Weekly:

One of Rex's avowed goals for his Dirt Nasty project is to be "the rap Tenacious D," a legit musician out for laughs (his YouTube bio reads: "I, Dirt Nasty, am a complete idiot ... Enjoy my world"). But he's not an idiot -- he's just willing to play the fool, splitting the difference between Deuce Bigalow and Californication's Hank Moody.

Still scoffing? Weigh the odds: The Bay Area-raised personality achieved mild notoriety as a mid-'90s MTV VJ, a profession whose shelf life rivals pets.com employees and The Bachelor contestants. Logically, his career should be deader than Dan Cortese's Agassi mullet. The prologue to his self-deprecating faux-reality show, Rex (2009), described him as a "struggling actor" whose "controversial masturbation video [more about that in a second] made him famous. He's had no controversy since, and boy, could his career use it."

This is half-true. Rex is wrongly branded "famous for being famous." He's actually famous for being almost famous. Fueled by the tabloids and TMZ, modern fame is like horseshoes and grenades: Proximity counts.

Proximity to Charlie Sheen these days, however, counts in all sort of unpredictable ways.

According to TMZ's description of the debacle:

According to multiple people inside the Fox Theater ... the majority of the audience is heckling, not only Charlie, but his buddy Simon Rex who came out and started rapping. We're told Charlie started the show with a Q&A session -- answering audience questions about everything from fave porn stars to crack cocaine. Then Charlie played clips from a network interview he did and ripped it apart.

That went on for about 30 minutes ... and the crowd was initially cheering for Charlie. He even sent out a twitpic of the enthusiastic audience.

But then the crowd got ugly.

We're told Charlie called on Simon Rex for backup ... sending him on stage to rap -- and when that backfired they played the new track, "Winning" ... which Snoop Dogg recorded for Charlie.

In case you are wondering what kind of music Charlie Sheen's "musical director" Simon Rex (aka Dirt Nasty) has produced for the strangest Megastar ever to win the pop culture game, here you go:
