I think it's better that she doesn't promote that much, because she can get over exposed!
a new album every year!
every 2 months a new single + video
on magazin covers & newspaper every day/week
if she would attend on every show people would get tired of her
+ since she took a long break, her performance are really theatric + she is proving that she is a vocalist!
If she would performe everywhere every week or every 2nd week she would not have time to rehearsal the song --> she wouldn't slay us with her performances! Cuz everything takes his time, esp. the dancing!
