Justin Bieber in LA: Driving Diddy's Lamborghini, in concert

Justin Bieber hit the City of Angels for a concert on July 20.

But before performing his latest stop on the My World Tour, he took Diddy's Lamborghini out for a spin, reports the Daily Mail.

Wait, what?

Apparently, a year ago, Sean "Diddy" Combs promised a 15-year-old Bieber that he could drive the rapper-producer's white Lamborghini once he turned 16. Biebs turned sweet 16 in March, so once he hit LA, Diddy made good on his promise.

Bieber didn't go crazy though and go drift racing through the streets. Instead, the pop star took Sean Kingston out ... for some frozen yogurt. Man, that Bieber sure likes his yogurt.

We're assuming that this is a loan only. His mentor Usher had actually given him a brand-new Range Rover for his birthday.

Once Bieber was done with his cruising and snacking, he got down to business, singing to a screaming crowd at LA's Nokia Theatre in downtown.

It's difficult to hear, but we like this footage of him singing "Never Let You Go" because it's pretty close up and is a nice change from his aerial acrobatics.



And then there's the classic "Baby" of course:
