After going to her concert the past two days I just wanted to share that the booth is run by Covergirl! You either have to a 18 or older or 16 I don't really remember, but it's one of the two! Your birthday just has to be in the given month so for example I went on the 2nd and 3rd and if my birthday was the 31st of July it still counts! YES they check your ID. They take a picture of you and write down your birthday, age, section, seat number and row! Hope this helps!
