It was well reported when Usher gifted his protege, Justin Bieber, a Range Rover on the lad's 16th birthday. And that exchange makes sense. But you know what's more remarkable? Diddy -- who, unlike Usher, doesn't have a financial stake in Bieber's success -- made good on a promise to give him his Lamborghini Spyder. Mere months after Bieber got his driver license, he was spotted in Los Angeles, driving Diddy's pricey sports car like he owned it. It remains to be seen whether he truly did own it at the time, but would you want to give up such a sweet ride if it were loaned to you?
