She's actually a really pretty lady

Could it be because of makeup?

Exactly

even without makeup her eyes have a beautiful shade of grey and light green-. I think she looks better without makeup and crazy wigs :)

Yeah still ugly

yeah same here... I also find Nikki Minaj beautiful when she's being simple with her outfits

Agreed. This is the case of 99.9% of female celebrities, and even some male ones (though I'm not sure I'd refer to guys who spend so much time on their looks as "male"). People see pictures of them after they spend 5 hours in a beauty salon, and the picture is obviously photoshopped, but still everybody praises them for their beauty or whatever. When you see them without all this "help", you're just like...meh.

Not really, without makeup she is really really gorgeous

Well, as gorgeous as a ferret can be, anyway.
