So what do pre-teens and teens spend money on these days? When it comes to iTunes, Ke$ha and Justin Bieber are the first two names that come to mind. And it’s just so happens that the two current untouchable teen dreams share the same Pisces birthday. Ke$ha (whose real name is Kesha Rose Sebert) was born March 1, 1987, and Justin Bieber was born exactly seven years later on March 1, 1994. Both are comfortably dominating the prepubescent airwaves with catchy tunes, distinct looks, and seemingly good intentions. Though historically, Pisces has not been a sign that tends to produce an internationally renowned pop stars. But these two also have a confident and attention-loving Moon in Aries in common, making their connection even more convincing.
