Thanksgiving is upon us, and if there's one thing we can be thankful for (in Hollywood, that is) it's celebrities who make an effort to give back to the community... and what better way to do that than with charities!Britney Spears Brit%26CoCharities.jpg
First there's the Britney/X17 online eBay auction - which is still going! - 100% of proceeds from the sale of an autographed Blackout CD will go to UNICEF!

Then this Thursday in Vegas Paris Hilton raised a whopping $105,000 for cancer research, which'll benefit the Nevada Cancer Institute...

Meanwhile Paris' pal Nicole Richie is asking that all intended baby gifts for her and Joel be donated to the Richie Madden Children's Foundation, which supports mothers in need. How thoughtful!

Don't forget the Heroic Hayden Panettiere's recent efforts to help save the dolphins in Japan!

And last but not least is Zac Efron, sporting an OmniPeace t-shirt while playing ball this week. Looks like everyone's doing their part to help others and raise awareness... and we salute them!
