This SimDay comes with a nice tool, similar to the Make-a-Date tool. In fact it's the same, except that it makes celebrities (like the SomeBodies), and you can also set their star level. However, I've tried it out a bit and it's far from perfect. The preview skin doesn't always look right, and it seems to catch a lot of Randy's when importing Sims using non-English versions. You can download the 3 Mb big file from this page. Along with this tool comes a Celebrity Exchange, where you can upload and download user-made celebs. You can find that right here at the official site.
