But judging from the way Xzibit flashed his ridiculously expensive diamonds in Vegas Wednesday night, someone forgot to tell him about the house trouble -- and the more than $500,000 he also owes in back taxes.

X-to-the-Z rocked an iced out necklace and a really, really expensive watch to ROK nightclub -- where he partied like his name was Nero.
In addition to nearly losing his home in Woodland Hills, California -- it was reported last week that the IRS filed a $205,485 lien on X in L.A.County for non-payment of his 2007 taxes, and yet another one for an additional $296,355 for 2006.
Maybe that's why he was double fistin' the vodka ...
