On the fourth hour of 'Today' (weekdays, 7AM ET on NBC), Kathie Lee Gifford and Hoda Kotb previewed a clip from Lindsay Lohan's surprise interview on 'The Tonight Show With Jay Leno,' which is set to air tonight.

In the clip, the actress chalked her troubles up to youth, but stated that she's "focused" and "in the clear now." Last week, Lohan was sentenced to 120 days in jail after a judge ruled her alleged necklace theft violated probation.

"I think that ... being young and being in the position that I was in, you don't really take the time to appreciate what you have. And it all is kind of a whirlwind and people make decisions for you," said Lohan. "But, I'm not a kid anymore. I'm 24. I've made a lot of mistakes and I recognize that. But, I'm in the clear now and I feel like, as long as I stay focused, then I will be able to achieve what I want to achieve."
