I don't have enough information to determine who Jolene is in this story. She could be an ordinary person, a public figure, or someone known only within a specific community.
Not likely to be completely true. Maybe it has some roots in reality, but it's likely a combination of real and made-up elements to create a compelling narrative.
It's hard to say for sure. Some songs are inspired by real events, but might have fictional elements added. So, it's possible Jolene has some basis in truth, but it could also be mostly made up.
No. Writing fanfic that involves Beyoncé in a lesbian relationship without her consent is unethical. Beyoncé is a real person with her own identity and privacy rights.
The 'beyonce love story' could represent Beyoncé's exploration of love in her music and life. Her music often tells stories of love, from passionate romances to self - love. It might also be about her relationship with her fans, as she shares her love through her performances and art.
I'm not really sure of specific 'beyonce horror stories'. Maybe some people might consider overzealous fans' behavior as a kind of horror story. For example, fans getting too pushy at her concerts or stalking her.
