Check her wikipedia, she definitely got the boob-job. She had it done June 1st 2007, and was back in the business on June 26th 2007. So anything relatively new she has the boob job in. http://en.wikipedia.org/wiki/Katja_Kassin
If she quits then porn can just go fuck itself in the asshole. I swear. There just isn't going to be anything, or anyone, worth watching after Katja quits.
