As we unwind from Thanksgiving 2012 and think of how blessed we are, we wanted to give a shout-out to a few celebs — they have a ton to be thankful for, but make a point of giving others a lot to be thankful for as well! Whether it's for the donation of money or time, we (and countless others) are thanking their lucky stars for these stars!

Awesomely, there are way too many charitable stars to even keep up with these days. This is just a sampling of some celebs and their causes, and we've provided links below so you can find out more about a certain cause if you want to learn more about them.

We hope everyone had an amazing Thanksgiving!
