An app for finding where your favorite celebrities will be (concerts, meet and greets, etc)

So basically there would be a database of famous celebrities, and you can choose who you like, and it will display if they will be in your area (be it meet and greets, concerts, etc). I think this could be useful for people who are interested in meeting their favorite artists or would like to attend their shows. There would be a feature to “track” the celebrities and get notifications when they will be in your area. Also there can be a thing where you can follow certain venues and get a notification when a certain celebrity will be performing at a specific venue. It would also be cool to have a feature where you can track the where-abouts of a celebrity to see where they have been and if they post about concerts then it would get linked to the database automatically. The app could also feature interviews or vlogs that the artists have posted on Instagram or youtube so you could get more familiar with their personality (for those who are not already familiar). The app would also provide users with information on upcoming concerts and meet and greets in their area, and recommend the events they might enjoy based on their preferences.
