Can you say BALLINNNN?! Apparently “recession” is not a word in Soulja’s dictionary, because for his birthday yesterday, he dropped BIG bucks on a private jet for himself and his crew. FInd out exactly how much he spent after the jump.

A member of Soulja’s management team tells TMZ… 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.
