One day after posting the video, Al-Mazbouh removed the post and uploaded another video where she apologized "only to the respectful" Egyptians that have shown her support, while attacking Facebook users who insulted her through private messages.
Mazbouh was initially handed down 11 years but the sentence was later reduced to eight.
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.
In a similar incident, former actor and model (and Egyptian woman) Amal Fathy was detained last month after she posted a video on social media criticising the government for failing to protect woman from sexual harassment.
El-Mazbouh has apologised in another video, claiming that she "didn't mean to offend all Egyptians".
The allegations drew a strong reaction online, with some Egyptians calling for Mazbouh's arrest and lodging a complaint against her.

"You deserve what Sisi is doing to you, I hope God sends you someone more oppressive than Sisi", Mazbouh said.
As reports EgyptIndependent, the charges against Mona al-Masbah included the "deliberate dissemination of false information aimed at undermining public morals" and "insulting religious feelings".
Emad Kamal, Mazbouh's lawyer, has expressed that "with all due respect to the judiciary, this is a severe ruling".
The court's verdict is not final and will be appealed on 29 July. She was also fined 10,700 Egyptian pounds (around $598). "It is in the context of the law, but the court was applying the maximum penalty", he said.
The prosecutor referred Madbouh to an expedited trial over the video.
In 2006, the woman underwent surgery to remove a brain clot that has limited her ability to control her anger, the lawyer said, Reuters reported.
