Soulja Boy Drops Major Cash For His Own Personal Jet

Well looks like Soulja Boy is

having no problems with cash he just recently dropped $35 million on his own private jet! Soulja Boy just turned  21 this week and splurging cash like its water!

Tmz says

A member of Soulja's management team tells us ... the kid bought himself a G5 jet as a birthday present to himself this week.

The jet cost $35 mil ... but that's just the beginning. We're told the birthday boy is dropping an additional $20 million to pimp out his ride with all sorts of cool stuff ... like 12 custom Italian leather seats, flat screen TVs, 4 liquor bars, a special travertine tiled floor, and Brazilian hardwood cabinets.

We're told S.B. is also gutting the in-flight lavatory -- and replacing it with a giant, LUXURIOUS bathroom. Oh, he's also giving the jet a custom paint job ... to include his logo.

And if that's not enough for someone's 21st -- we're told Soulja's also spending $300,000 to throw himself a blowout birthday party at a Miami nightclub tonight ... and Dwight Howard, Bow Wow, and Sean Kingston are all expected to attend.

I'd like to see more artist dropping cash on charities and fundraisers instead of material things.
