Soulja Boy's 21 st Birthday Gift To Self - $55 Million G5 Jet

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.
