Lindsay Lohan may be used to tabloid gossip about her own life. But she's fighting mad over recent rumors swirling around her 14-year-old sister Ali.
The 22-year-old actress took to her blog Thursday to slam online speculation that her little sis may have undergone breast augmentation. In fact, Lindsay said she was confronted by a photographer who yelled, "What do you have to say about people commenting on your sister's implants?"
"It made me feel a bit sick to my stomach," Lindsay wrote on her MySpace Celebrity Blog.
The actress - who's preparing for her recurring role on Ugly Betty - said she's "not judging" people who do have cosmetic surgery.
