She may bear the grunt of tons of tabloid gossip, but Lindsay Lohan does not tolerate gossip about her little sis, Ali! Recent rumors have been flying about 14-year-old Ali having undergone a possible breast augmentation, but Lindsay is saying "No way!"

Lindsay responded to the rumors by facing the world in her MySpace Celebrity Blog Thursday night after she heard a photographer ask her, "What do you have to say about people commenting on your sister's implants?" Lindsay wrote that "It made me feel a bit sick to my stomach," She said she's not "judging" people who have had cosmetic surgery, "But all in all my mother taught us to appreciate what we have been given," she wrote. "Nor would [my mother] ever encourage, or allow a 14 year-old child to alter her body." Maybe preparing for her recurring role on Ugly Betty has taught her even more about true beauty!
