Sadly they’re gone.
Good Lord almighty, I had no idea she had done that. 
She had some issues with one side (I think it was the left one) which was removed earlier and had the loose skin and now it looks like she had a lifting to a smaller more common size.
Well, that's the way most big bust models went sooner or later.
I hope she is happy and be sure she might find satisfaction for herself even without having them anymore.
But remember she did great content which will last forever
