Would another woman doing this bother you?

My husband is in a band and he does concerts and stuff and has a decent following. I understand that girls and women may get attracted to him. He's very attractive and I'm usually secure in my relationship but I personally feel like one fan has crossed a line. Because she's online and on tiktok pretending to be his wife. My husband doesn't really post me on Facebook. He has a Facebook but it's mainly to promote his band and music. I have pictures of us on my Facebook. He posts nothing about his personal life. So she's pretending she is his wife. I got sent this by a friend and I don't think she's doing this as a joke. She never states it's a joke and I think it's extremely disrespectful and even my husband finds that creepy because he actually took a picture with her when he met her at one of his concerts. Which deep diving she had made her profile picture on Twitter and she posts sexual stuff like " Get you a man who isn't afraid to lick the kitty." Which again, she's pretending my husband is HERS. Isn't this borderline sexual harassment? She followed my husband but he blocked her. Didn't even have to ask him because he found it creepy. I wasn't going to say anything to her until I found out she found my Facebook somehow and took a Christmas picture of our 6 year old son when he was a BABY and it's pretending it's her and my husband's baby! I reported that and I want to message her to back off and honestly want my husband to shame her publicly by telling everyone she's crazy and not his wife. I feel like I'm not overreacting because she's crossed so many boundaries that even my husband was uncomfortable.
