After dropping $55 million on a tricked out private jet for his 21st birthday this week … rapper Soulja Boy celebrated turning 1 year older in another expensive way by spending $300K to throw a huge party for himself in Miami!

Hosted at Miami hotspot Club Play Friday night (Jul 29 — 1 day after Soulja’s birthday), the party saw appearances from Trina, Sean Kingston and even Justin Bieber! (not pictured)
