Should I tell my mom the disgusting comments her students made about her?

Hello. I (19M) live with my mom (49F). My mom is a pretty woman and looks way younger than her age. My mom is a high school teacher and last week I went to her wokplace with her. During her classes, I was sitting at the back of the classroom. When I was sitting at the back, I heard some students making very disgusting comments about my mom.

I heard male students talking about my mom with words such as "bitch" or "slut". I heard one of them saying that my mom was a "horny bitch" and she was going to have sex after school. I heard one of them saying that my mom was dressed like a "whore" and she was naughty for wearing red nail polish. My mom was actually wearing a red turtleneck sweater, skinny jeans and white high heel sandals. Her finger nails were not painted but her toe nails were painted red. I heard some male students making comments about her boobs and her ass.

I also heard some female students saying how hard she was trying to look sexy. I was really shocked and disgusted by these comments. I don't know if I should tell my mom about these comments. Should I tell her what I've heard?
