Mazbouh was arrested early June in Cairo Airport after a video she posted on Facebook went viral.
The allegations drew a strong reaction online, with some Egyptians calling for Mazboh's arrest and lodging a complaint against her.
She also accused men of sexually harassing her and even called Egyptian women "prostitutes". In that video she described Egypt as a "son of a bitch country" haven completed her stay in Egypt.
Mazbouh was initially handed down 11 years but the sentence was later reduced to eight, and fined 10,700 Egyptian pounds (around $598).
A Cairo court found her guilty of deliberately spreading false rumours that would harm society, attacking religion, and public indecency, judicial sources said.
The lawyer filed an appeal against the jail verdict and it will be heard before an appeal court on July 29. She added that most of her first video was narrated in a Lebanese accent, and that is why most Egyptians didn't understand what she was saying correctly.
Kamal further explained that Mazbouh suffers from depression and struggles to control her anger due to the removal of her brain clot in a 2006 surgery.
In May, Egyptian authorities had arrested activist Amal Fathy after she posted a video online in which she spoke about her negative experience in and outside a local bank branch. "It is in the context of the law, but the court was applying the maximum penalty", Kamal said, according to Reuters.
She also lashed out at the state for the prevalence of widespread begging and and spoke of an incident in which money was stolen from her during a previous stay. Mazbouh also claimed her original video was not meant to be viewed by the public, and that the post was a "private one", which was only accessible by 25 friends.
