Blac Chyna went from wheels down to wheelchair up at LAX Saturday, and it's unclear why she needed an assist.
She can clearly walk, because she got out of the chair at some point and hoofed it to the car. Our photog didn't ask why she was in the chair, but she probably wouldn't have answered.
She was sure mum on a report Rob Kardashian threw shade on her newly-minted rapping career, but gotta say ... why throw shade on Kevin Federline ... "Popozao" is awesome.
