Amanda Bynes plastic surgery, breast implants?

Tori Spelling breast implants surgery
Much to my surprise, there have been quite a few rumors swirling around which suggest that Amanda Bynes has undergone plastic surgery for breast implants, and while her breasts do appear to be somewhat larger, i attribute this to a late "21 year old" growth spurt which she appeared to have went through a few years ago.

Well at least that's the only explanation i was able to conjure up, because i don't see any giveaway signs of breast implants or plastic surgery of any kind.
