DJ Diesel -- aka Shaq -- was once again bringing the house down Friday night .... when he was scratching to a huge crowd for his annual Fun House party before the Super Bowl, which was packed with a who's who of celebs.
The NBA icon held his big bash at Mardi Gras World -- about a mile from Bourbon Street -- where he once again ruled the DJ booth with sick beats, bumping them for the crowd.
Make no mistake .
