Yeardley Smith — who voices Lisa Simpson on the hit Fox toon — has filed for divorce from her husband of four years, Daniel Erickson.

According to a petition filed Wednesday in Los Angeles Superior Court, she cited irreconcilable differences, TMZ.com reports.

She is requesting that she not be ordered to pay spousal support.

It isn't her first split: In 1990, she wed actor Christopher Grove but called it quits in 1992.

Smith, 43 -- who originally auditioned for the role of Bart -- has admitted that she battled bulimia before the age of 13.

She said her eating disorder got worse when she failed to achieve her personal goal of winning an Oscar by age 30.

"I would turn all of my anger and disappointment in on myself, which would be an instant unfailing trigger for my bulimia, which was already raging out of control," she told Newsweek in 2005.

She said she hasn't binged and purged since 2003.

Playing Lisa Simpson - who had an eating disorder - has been a way "to work out a lot of my own childhood social angst," Smith has said.

"She's a fantastic legacy," she adds of the toon. "I have a complete understanding that she and the show itself are now so much a part of the fabric of our culture, in this day and age, that it would be foolish to think, or even try, to somehow shake it or make it less than what it is."
