Rapper Soulja Boy celebrated his 21st birthday on July 28th by buying himself a pricey present -- a $35 million private jet that he plans to spend another $20 million renovating.

Those renovations will include gutting the bathroom, a custom paint job, 12 Italian leather seats, four liquor bars, and Brazilian hardwood cabinets.

The newly-legal performer is also dropping $300,000 on a birthday bash at a nightclub in Miami, Florida this weekend, which many other rap stars are expected to attend.

Maybe MC Hammer needs to talk to the guy about the fleeting nature of fame and the perils of overspending.
