"Famous in 12" chick Jameelah Artiaga wants to set the record straight about her boobs ... they're 100% real -- even though tons of people online think she's got fake knockers.

Artiaga says her size 32DD tatas are far from fake ... and she doesn't understand why so many people on Twitter accused her of having implants after the show's debut.

Jameelah adds, "I've worn the same bra size since I was 16!" 

and her family are part of TMZ's experiment -- to see if a family desperately seeking fame can move to Hollywood and achieve their goal in 12 weeks. It airs Tuesdays on the CW at 8 PM.
