"You will never see me in a nude scene," Lohan tells Access Hollywood on Wednesday. "Then there's no mystery for my private life."
The young star, who says she wants to be a respected actress, tells the show, "I don't think that's what's needed to win an Oscar for me."
On Wednesday morning, Lohan also told Today's Matt Lauer that if she had had her way, attention would be paid to her acting, not to her social life.
Admitting that she hates the word "partying," the star of Herbie Fully Loaded, which opened Wednesday, said that she's a professional who would like a career just like Jodie Foster's.
"She's my main person I always look toward," said Lohan, who turns 19 on July 2. "She was able to make the transition" into adult roles after a career as a child star. "I don't just want to be a celebrity," Lohan emphasized. "I want to be an actress."
With Lauer telling her that public perception of Lindsay Lohan is someone who "has romances with older men and parties without boundaries," Lohan responded: "I don't hang out in clubs as much as they say I do, I go out with friends and go out to dinner."
The conversation then turned to her weight. Lauer pointed out when he first started interviewing her, she was more full-figured. "I just hit puberty!" she shot back at him. As for her new, slimmer self, which also has been the subject of tabloid speculation, she said: "You grow up. You work out. You eat healthier. I was (accused of) having implants, then of taking them out."
Finally, when asked if she had any career advice for her younger siblings, Lohan said: "Don't go out anywhere. Stay in the house and don't leave."
