Mazboun's video, which she posted on her social media account, went viral when it was later published on YouTube to be viewed by hundreds of thousands of viewers.
Lebanese news website al-Modon said in an editorial that Cairo has sent "the clear message that tourists are not welcome in Egypt".
Initially she was sentenced to 11 years in prison, but that was amended within hours to eight years, the judicial source said.
The sentence comes after she posted a 10-minute video in which she used profanities to describe her vacation in Cairo where she says she was sexually harassed.
"Here bitch country! Yes, in all the world no people dirtier than the Egyptians!"

Police officers guard a cordon in Salisbury, one of five locations in the city and Amesbury under investigation. Police are continuing to hunt for a contaminated container which they believe was handled by the pair.
In an interview with Al Arabiya English, he said that his daughter loves Egypt, and that this was her second time visiting Cairo. She said she faced verbal harassment, launching a scathing attack at the bank's employees, which then prompted the bank to file a lawsuit against her.
She was charged with "deliberately broadcasting false rumors which aim to undermine society and attack religions".
Of course, God willing, the verdict will change.
An appeal court will now hear the case on July 29, according to Ms Mazbouh's lawyer, Emad Kamal. She also expressed her disgust at the standards of Egyptian restaurants, and insulted President Abdel Fattah al-Sisi saying the country "deserved what its president was doing to it".
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. "It is in the context of the law, but the court was applying the maximum penalty".
