The Mean Girls actress, who has been to rehab several times and was recently sentenced to three years' probation for stealing a necklace, has admitted her mistakes have deterred her sibling Ali from doing the same.
Lohan, 24, said: 'My sister Ali is a nice person too. She's seen a lot of stuff that I've experienced and she knows exactly what not to do. So she kind of knows better through watching me.'
Lindsay also said that she is not worried that 17-year-old Ali will be tempted by Hollywood vices because she is 'tougher' than her.
