Lindsay Lohan received a surprising standing ovation when she made a guest appearance on the "Tonight Show," which was pre-taped on Monday and will air tonight.
The actress said her 120-day jail sentence was "shocking," adding that she felt "kind of numb." Lohan, 24, believes she has matured and can stay out of trouble. "I think that when, you know, being young and being in the position I was in, you don't really take the time to appreciate what you have and it's all kind of a whirlwind, and people make decisions for you. But I'm not a kid anymore -- I'm 24, I've made a lot of mistakes and I recognize that. I'm in the clear now, and as long as I stay focused, I can achieve what I want to achieve."
Lindsay confirmed she will return to work in the upcoming film, "Gotti, Three Generations," starring John Travolta.
Lohan is expected to begin her 480 hours of community service on Monday at a women's shelter in downtown L.A. and will also spend a portion of the hours working as a janitor in the County Morgue.
