lady ga ga= new david bowie?

i was fillipin thru channels one rainy day and when i came across vh1 i happened to glimpse at a vid of lady ga ga wearing what closely resembled a ziggy stardust lightning bolt. so two things: 1) is she trying to be like david bowie? 2) are all popstars, including manson, a buncha choke artists with no originality or creative spirit.
