Nadya Suleman, better known by her nickname "Octomom," has pleaded not guilty to yet another welfare fraud charge, the Associated Press reported on Tuesday.

Suleman, who famously gave birth to eight children in one day, made a court appearance in Los Angeles this week to plead not guilty to four counts of welfare fraud.

The single mother to octuplets and six other kids is slated to appear in court again on April 16, AP reported.

Suleman has been accused of failing to report earnings totaling to nearly $30,000 in 2013. Prosecutors tacked on additional charges a month after submitting the original claim alleging the Lancaster, Calif. resident received almost $10,000 in MediCal benefits illegally, according to the Los Angeles County District attorney's office.

CNN reported in February that Suleman pleaded guilty to the initial three welfare charges against her. District attorney officials said they're seeking restitution totaling to almost $26,000.

The 38-year-old mother of 14, who collected food stamps for her children, reportedly left out claims on earnings she made doing cameos, appearances and television spots, Deputy Dist. Atty. William Clark wrote in the original complaint.

Suleman reportedly did a porn video, posed topless for various publications, danced in a Florida strip club, and took part in celebrity boxing matches to make money.

Suleman, who was on a government program when she gave birth to her children via in vitro fertilization, allegedly received $16,481 in welfare money from January to July of 2013. That included $9,814 from the CalFresh food program and $6,667 from the CalWorks financial aid program, the Los Angeles Times reported.

If she is found guilty, Suleman could spend up to five years behind bars.

Suleman, whose real name is Natalie Denise Suleman, was launched into the spotlight on Jan. 26, 2009 when she gave birth at a Southern California hospital to eight children, all of whom became the world's longest-surviving octuplets.
