growing up
A term female celebrities will often use as an excuse to turn into a total slut/whore/courtesan/prostitute/harlot. They usually start their careers at a young age, with a fake innocent image. When they are close to their twenties, new, unneccessarily slutty and horrendous songs and music videos will be produced. More often than not, they will be hated by the world, contrary to their beliefs that they will sell even more. What a bunch of whores.

Another excuse from them would be things such as, "im just showing my true self, the innocent me is just a fake image"
In other words, they are nothing but a pure bred prostitute.
