Are we too obsessed with celebrities like Chappell Roan?

Chappell Roan has posted on TikTok about "creepy behaviour" she's experienced in person and online. She’s one of this year’s most successful popstars with a growing fanbase, but are some of those fans starting to overstep the mark?

Pete Allison, our BBC Newsbeat reporter, tells us what Chappell has been saying.

We also look at K-pop fandoms with our Bilingual Reporter, Julie Yoonnyung Lee. There’s even a word in Korean to describe an obsessive fan who invades the privacy of a star - sasaeng.

And Veronica Lamarche, a psychologist who has done studies on parasocial relationships, tell us what signs to look out for that your interest in a celeb has turned into an obsession.
