020816-bella-hadid-instaBella Hadid's either studying for medical school or she's just a very, VERY caring friend willing to conduct free breast exams ... on camera. Thank you, God.  

So many things to envy here -- Bella's bikini bod, the 82 degree winter weather and yes ... Bella copping a feel on her singer pal, Jesse Jo Stark

All signs point to The Weeknd's GF shaking off that whole getting a crap table thing at Craig's. 

Thanks for the pics, Bella ... said all of Minneapolis where the thermometer reads 12 degrees.
