Boys and their toys!

Soulja Boy turned 21 on Thursday, and the rapper bought himself a $55 million private jet for the occasion.

A member of Soulja's management team told TMZ that the "Crank That" singer (real name: DeAndre Cortez Way) bought himself the G5 jet for $35 million. But the birthday boy dropped an additional $20 million to pimp out his ride -- with Italian leather seats, flat screen TVs, liquor bars and Brazilian hardwood cabinets. The birthday boy even had his logo painted on the side of the plane.

But Soulja's celebrations won't end with the purchase of a private jet. He's throwing a lavish party Friday night at a Miami nightclub. Fans are invited to watch the fete online by paying $2.99 on Web pay-per-view at
