its pronounced kesh-uh.
its insane that she blew up so much, i've known that chick for a while. i used to hook up with one of her best friends a few years back, but we've stayed really good friends before and after the hooking up stage. they are just crazy party broads who get wasted and do dumb shit. i always knew kesha did music shit but then one day my girlfriend was talking about her and how her album was number one on billboard and shit. it blew my mind.
