Before Lindsay Lohan heads to an L.A.-area morgue for her community service, the troubled starlet stopped by the Tonight Show for a surprise chat with Jay Leno.

In an interview scheduled to air Tuesday night, Lohan, 24, clad in a silky black pantsuit, said her punishment felt "shocking" and revealed she feels "kind of numb."

"I'm not a kid anymore," she said. "I'm 24. I've made a lot of mistakes. I recognize that, but I'm in the clear now and I feel that as long as I stay focused, I will achieve what I want to achieve."

According to insiders, the starlet received a standing ovation from the audience when she came out.

Lohan also talked about resuscitating her film career, starting with a role in the upcoming Gotti: Three Generations, in which she's scheduled to play Kim Gotti, the wife of John Gotti Jr.
