Celebrities were really diverse this week with their beauty looks. The best ones proved that you can look amazing all dolled up -- see Katy Perry's glamorous red carpet face -- and equally great with hardly any makeup. Jennifer Lawrence braved the masses and appeared at "The Great Gatsby" premiere fresh-faced. And she looked beautiful, of course.
Most of the worst looks this week were a result of makeup mistakes that could have easily been fixed. Jessica Paré put a little too much powder on her face and Bo Bruce suffered a serious case of clumpy mascara. We could give her a few tips on how to prevent that next time.
