1:58 PM PT -- Turns out Blake's mystery blonde is none other than Francesca Aiello -- the owner of Frankies Bikinis. Good choice.
Even in the off-season, Blake Griffin's rebound skills are on point -- just ask the blonde chick he was sucking face with in his Land Rover.
The NBA star and his mystery woman are definitely living on the edge. Saturday's date night included riding around on Bird scooters in L.A. ... which, considering Blake's history of injuries, might not have been the smartest option.
A better, safer idea? Sitting in Blake's whip and making out ... which they also did.
No clue yet who the lucky lady is, but she's the first woman he's been spotted with since he and Kendall Jenner broke things off.
We think we can safely speak for the entire Pistons organization here: Date all ya want, Blake ... but lay off the Birds!
