Soulija Boy finally joins our list of ‘rich jet setters’! The rapper, who turns 21 this Thursday, has not only bought a little nice birthday present– a tricked-out jet, a Gulfstream G5 with a $55-million price tag—but has spent a whopping $35 million on the upgrades. Think travertine floors, Brazilian hardwood floors, Italian leather seats, and four liquor bars (he’s 21, c’mon!). And, of course, a custom paint job of the Soulija Boy logo. And just in case you are wondering, is that all? The boy is throwing a $300,000 birthday bash, which will be viewed on $2.99 per view. Now that’s what we call having your cake and eating it too!
