"I was cracking up," Lohan (who now prefers to be called Aliana, professionally) tells Page Six Magazine about all the nip/tuck talk.
"Because, like, when would I do that? I'm 17 years old. That's not legal! I would need my mother's signature, and do you think my mom would sign off on that? No! It's not the right thing to do. It's stupid. I don't listen to it. It's absolutely not true."
Not surprisingly, the conversation with Lohan, who recently signed on with Next Model Management, turns to her troubled sister—someone she has the utmost respect for.
"I admire how strong she is," she says. "She's an independent woman."
And while Lohan admits that she has been offered drugs in the past, the teen is quick to point out that she's never touched them.
"I just say no," she insists. "I'm lucky enough that I had my sister to learn from...That's why Lindsay and me are so close, because we're able to talk about those things together."
