Gwen Stefani Breast Implants

Gwen Stefani before and after breast implants plastic surgery?

Gwen Stefani is the lovely fashion conscious, energetic lead singer of the hugely successful ska/rock band, No Doubt.

Has anyone else noticed a change in Gwen's appearance, lately?

There is no doubt, there is differently some extra cushion in the breast area of ms Stefani, but the question remains, what type.
Is Gwen Stefani sporting an extremely padded bra or did she get a boob job?

Judging from these before and after pictures, what do you folks think? Plastic surgery or perhaps a water bra?
