Regardless of how famous they are, and despite the star treatment they receive all the time, many celebrities make it a point to give back to charities, organizations, and sometimes to the very communities from which they came.

Some of Hollywood's glitziest stars, including Ed Sheeran, Avril Lavigne and Ashton Kutcher, are more down-to-earth than some may think, sharing their wealth and kindness to support the greater good of the world.

Last week, we showed stars who have given back over the years, but this time we thought we'd recognize the stars who used their star power to promote causes greater than themselves this year. You'll probably freak out to learn how much Justin Bieber and Emma Watson earned for social causes by auctioning off their prized possessions, but even more teary-eyed to hear about the heartwarming gifts stars like Robert Downey Jr. and Taylor Swift gave to their adoring fans.

Check out our gallery above to see the celebs we thought made some pretty incredible contributions this year.
