My friend is a back up dancer for BTS and has been talking about the group a lot, I need to be a good friend, so I borrowed the Jimin sex tape, but it seems like it's fake?

My friend and I are both women. We are both in our mid 20's. She's one of the backup dancers for BTS. What this means is that she does the choreography of the BTS songs with them during live performance, but she is not a member of their group. She has been talking a lot lately about BTS. Like so, so much and it's starting to make me and a lot of other people uncomfortable. I've tried talking to her about it before, but she won't stop. She's a petite, femme, Asian, non-binary woman. She's definitely not Jimin's type. I thought I could be a good friend and talk to her about the sex tape. But I looked at it and there's a lot of inconsistencies, and it appears to be fake. What am I supposed to do now?
