Lindsay Lohan is putting breast-busting rumours to rest.

Ali Lohan, Lindsay’s little sister and star of reality T.V. show “Living Lohan” is facing tabloid speculation that she got breast implants.

And big sister, Lindsay, is fighting back.

The “Mean Girls” star wrote on her MySpace blog:

“All i am trying to say is, is that, i was raised with a wonderful family surrounding me, of course we have our ups and downs, but all in all my mother taught us to appreciate what we have been given. Nor would she ever encourage, or allow a 14 year old child to alter her body.

“i am not judging people that do, but i am just saying that its not something that my family finds necessary to do, especially when you’re not even fully developed yet! It is hard enough being 14 years old and you have enough insecurities to begin with, then add being in the public eye… i just find it really disconcerting that people have to focus on the negative and that some people are sooooo bored with their own lives that they need to manifest lies to hurt another person.”

Lindsay went on to say that she just received some new clothes from Alexander Wang and that she missed Samantha Ronson, who was out of town.
