Katie Price, Gavin Henson, everyone from The Only Way is Essex, ditto Made in Chelsea, Geordie Shore, the Valleys, etc, though I wouldn't call them celebrities.
Just all the ones who take themselves way too seriously. Katie Price is a good example, as is P Diddy. Bieber is going down the same road too, not to mention his "beliebers" are ****ing annoying.
My nan is a belieber by the way... she's religious and has no teeth.
Honestly? The very nature of the people usually described as 'celebrities' means that I'd probably end up naming most of those who are widely accepted as one. I find myself baffled by the interest shown towards 'celebrity'.
Justin Bieber and Katie Price are the only celebs I despise. Justin Bieber for for obvious reasons, he's got millions of poor teenage girls brainwashed to believes he actually gives a **** about them. Katie Price because I met her a few years back, and she was absolutley horrible. Never come across someone so arrogant, ignorant and rude.
