From her own claims, she was a DD cup naturally, then she grew them to an I cup with natural methods. After she had her kids, they deflated and ended up smaller than they were originally and that's when she got depressed. Idk at what point the pic above was taken.
Also, breasts ending up smaller than they were originally after a woman stops lactating happens, and it's not nealy as rare as you might think. You can look it up.
