How come people say Lady Gaga worships the devil?

I read articles about it, but i think the music industry's is forcing them...idk... (beyonce for example) i mean, gaga is a roman catholic but why are her videos like that, why do people think its just HER and not the people who dress her in the music video costumers and the director? i just got in an argument to someone about that today. i told the person i respect their opinion but they wouldnt give respect to my opinion. (basically i did not even read any articles before this argument, but already had a bit of doubt because of judas)
