Celebrity caricatures - legal question

[Nova]

If I pay an artist to do caricature pictures of famous celebrities, can I use these images in my blog, website, game, app etc without being sued by the celebrities?

You're pretty safe with them, spitting image set the basis for that. Long as they are not libelous you're safe.

Many Celebrities quite like their caricatures as well, so if you keep i light hearted you could generate some good twitter traffic
