Lady GaGa has not only been a più obtrusive figure in the Musica industry, but her every appearance is a cause for cameras. her outlandish costumes excite everyone, whilst when she doesn't wear one it's even più of a reason to snap a picture! Ke$ha is just your average artist; te won't find paparazzi at her door night and day, and te could probably pik up the clothes she usually wears in your average clothing store. Therefore, there are più pictures of Lady GaGa because her style is più interesting, and every outfit she wears has something new to be immortalised. NOTE: This does not mean that GaGa is better than Ke$ha, musically o in her fashion sense, it's merely the truth.
Because Lady GaGa has been in the spotlight/ Musica industry longer than Ke$ha has. I mean duh! Lady GaGa had her first album come out in 2008 & Ke$ha's first album came out like just a few months ago. & even before then, there were lot's of pics of GaGa anyways, so that's why. But Ke$ha will end up will più pics just like GaGa so te have nothing to worry about. Here, I'll post a pic of her just to make te happy:
Lady Gaga has tons of different crazy outfits that are picture worthy. She has also been around longer. And she is probably invited to più foto shoots for magazines and other companies. Ke$ha doesn't have the outfits, the time o the popularity to have as much photos.
