I made my little sister cry ?

My sister is obsessed with this boy band I showed her a picture of the bass player and his wife she got really upset. Their drummer died so they don't tour much anymore in this country their from a different country she really wants to see them and meet him badly but we can't afford to go out of the country he just released a new song he's gonna be doing a new album this fall so hopefully he'll tour I hope he does she may end up hurting herself over him. How can I calm her down ? What should I say to her ?
