Diego  Ke$ha and Pitbull have very few things in common.  But if
there had to be one thing, it would be that they love to party,
and that’s exactly what they did at Chula Vista’s Sleep Train
Amphitheatre Sunday night.  Ke$ha, a 26-year-old L.A. pop
singer/rapper, did her best to open a night that truly belonged
to Pitbull. Known for her carefree, 20-something anthems and her
trashy-princess style, she offered few surprises in her 12-song
performance, showing little growth or creative enterprising
since her debut single “Tik Tok” hit the airwaves in 2009.  In
those days, Ke$ha was welcomed along with a crew of pop stars
like Katy Perry and Lady Gaga
