I have never heard clique pronounced like it rhymes with fleek. That one threw me off, since it's always pronounced the same as "click", at least where I am. I guess creek could have the same issue, but I would guess that's more localized.
It's pronounced cleek in British English but cleek and click in American English. I've heard both from American sources, so I think it's a regional thing. I know Smash Mouth pronounces it click based on Walkin' on the Sun.
