I don't pay much attention to Ke$ha, she is sort of like Beanie Babies. Really popular for a short time then one day you discover them crumpled up way in the back of your closet.
One thing I have noticed is that Ke$ha looks way older than her 24 years. Some girls simply look older than their age and some girls look beat. Ke$ha looks rough and those nasty hair extensions and Lady Gaga wanna be outfit are not flattering. Put on your big girl pants Ke$ha and get a real gimmick.
