Where can I get celeb photos?

I was wondering... where do most people get their celebrity photos for their blogs? is there any website that distributes them for free? I'm looking for photos i can use that only require attribute (a link back).

 

i sometimes get some in
http://www.zimbio.com/
http://cheezmozo.com/
http://www.celebrity-gossip.net/


mostly in zimbio

Does Zimbio allow you to do this? I want to legally do this.
