She's hot ... she can fight ... and ex-WWE diva Kelly Kelly can also change a flat tire all by herself.
TMZ has learned ... KK (real name Barbie Blank) was on her way to a bikini calender photo shoot last month when the tire on her Mitsubishi blew out.
But instead of whining like a helpless little girl, Kelly grabbed a tire iron and changed the damn thing herself ... refusing to deny the public the chance to see her in revealing swimwear.
Eventually, Kelly made it to the shoot. Here are the pics. You're welcome.
