If you’re a son of music mogul Diddy, you can expect totally awesome birthday presents. Justin, who recently turned 17, was treated by his dad to a brand new Maybach, but only after improving his grades in school.

PopEater reports that the rapper, who also gave Justin the same brand of car as present last year, on his sweet 16, believed it was time for an “upgrade” because he’d earned it.

So, Justin can now leave his old Maybach in the garage and take out the new one for a stroll: it’s the limousine version and it is believed to have cost Diddy $390,000.

Not that money is an issue with the music mogul. Plus, there’s definite improvement in Justin’s grades, so it was about time he got a reward for a year of hard work.

“Justin has turned himself around and is now an honors student, which he wasn’t before, so I wanted to treat him,” Diddy says of the present, as cited by the aforementioned e-zine.

“It’s a collector’s car so maybe he will use it for special occasions like on a first date, but like all my kids, he prefers the simpler things than the expensive things. Simple tastes,” the rapper adds.

As noted above, this is not the first time (and it will certainly not be the last) that Justin receives this kind of presents on his birthday: last year, Diddy gave him a Maybach and a check for $10,000, which the kid decided to give to charity, as we also informed you at the time.

Asked about whether he thought it was right to lavish such expensive gifts on a teenager, Diddy fought back saying the question showed people were still biased against rich black people.

“You don’t ask white people what they buy their kids. And they buy ‘em Porsches and convertible Bentleys, and it ain’t no question,” he said, as cited by PopEater.

“It’s really a racist question and put things back in perspective with money and the way that people still look at you,” he explained, adding that no one would dare ask Steve Jobs of Apple what he’s buying his kids for their birthday.
