Arrested in July, the dancers known as Bardis and Shakira, were also convicted of "broadcasting obscenities" for appearing in two video clips wearing flimsy clothes and making "suggestive" moves, the source said.
In June a court sentenced another female dancer, Reda El-Fouly to one year in jail for inciting debauchery but she appealed and the verdict was later halved.
Bardis and Shakira, who are seen in the video clip wearing short dresses with plunging necklines, can also appeal.
