The 22-year-old actress slammed the rumors on her blog on Thursday, saying 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 adds that she's "not judging" people who do have cosmetic surgery.

"But all in all my mother taught us to appreciate what we have been given," she wrote. "Nor would she ever encourage, or allow a 14-year-old child to alter her body."

Lindsay also admits being a little lonely without her gal pal.

"I miss Samantha [Ronson] cuz she's out of town :(" she wrote.

Ali Lohan accidentally auditioned for a porn director on the season finale of her reality show last month.

“Ali obviously had no idea about [director Peter Davy’s] past,” her rep told Us Weekly. “If she did know, she never would have auditioned for him.”
