She tells Vanity Fair, "(I realized) about two weeks ago. I literally realized what had happened in my life. I almost wish it hadn't hit me so late. I wish it had hit me gradually. I don't remember what city it was but we left (the venue) and after the show there were 5,000 people standing on stairways and platforms leading to a train station - I couldn't even see how far back. The car drove out and I said, 'Stop the car', and I got out and walked walked out and the scream was so loud, it was a roar. I went over to the fence and signed as many autographs as I could without them pulling me through.
"More fans than ever had been waiting for me outside after the show - meaning two hours of the most visually intense (show), in the heat, standing, jumping and screaming for two hours and then (they) waited for me for two hours - 5,000 of them. It was insane."
