Aly Michalka before and after breast implants plastic surgery?

Aly Michalka is a young budding actress, singer-songwriter and musician, featured on the television series Hellcats, and in movies including Bandslam and Easy A.

Lately, Ms. Michalka has been the target of numerous rumors concerning her bust size, many of which seem to be all but certain shes undergone plastic surgery for breast implants, however I'm not so sure these rumors are true.

My initial doubts were triggered after seeing this before and after photo, which many sites are using as a "fair" comparison, however Aly Michalka is significantly younger in the before photo, way before she fully developed.
Also, in more recent photos (above) you can see a much more mature Aly Michalka, completely developed and displaying very real looking breasts, with natural shape and hang.

With that being said, i suppose she could have received a "rare" realistic boob job, but I'll stick to my original thoughts and say, no plastic surgery for this young starlet. What say you?
