I thought she was a "string girl" and with them it is pretty much always just a guess unless you do an "imursion test" after having done one before she was ever implanted the first time and other than that there is "no real way to know"
She removed the " silly string " implant first developed by Dr Gerald Johnson of Houston back in the 1990's about 5 - 10 years ago. I believe Chelsea Charms is the last one to keep her original 2,500 ccs " silly string " that she got back in 1999. Originally put in the girls since it is much lighter than silicone or saline for the same volume, nobody foresaw how much it could expand and how it could be hard to control its growth. You could end up with one boob being much larger than the other one and generally speaking wildly asymmetric breasts are not marketable. Kayla, I believe, has expandable saline implants like Beshine even though not in the same scale.
