Savannah-Chatham police say they reported to a 50th Street park around 9:40 p.m. to find 22-year-old "Idol" finalist Stephanie Edwards fighting with 20-year-old Laquilla White.
According to a police report, the women were separated without any injuries.
Edwards told police the fight began after she received several harassing phone calls.
According to the Idol Web site, Edwards was an 11th place finalist in its sixth season, which aired in 2007. The site also lists Edwards' hometown as Savannah.
Both women were taken to the Chatham County jail where spokesman Deputy Ron Robinson says they each made $1,300 by midnight.
