She got implants and alot of people made fun of her so people are saying she maybe got them reduced or taken out and you can probably see the scars. That or maybe because of all the jokes and hate she's self conscious about showing them. I dunno.
She definitely got implants and wasn't showing them the last time she came back. I'm not sure if there was a complication or if she really did take them out from self consciousness or what, but it definitely comes back to the implants.
