This can be because they don't promote themselves, they have lame personalities, they never post on twitter, facebook. Or just because you don't like them! Which celeb do you find most annoying, especially the one's you follow.
I vote for Nicole Scherzinger. Go on her page, EVERY single status has a photo of her looking pretty making comments like "It’s important to be fearless yet vulnerable. It takes courage to do both" "Making a SPLASH! How's everyone's summer going?" "When I go onstage, I kind of turn into a beast sometimes. My alter-ego takes control." "I'm curious, how long have you been a fan?"
The comments are bearable, but the pictures omg.

It's like seriously **** off!
I get annoyed with Kelly sometimes as well, because she posts so inconsistently.
