Celebrity Causes You Missed on #GivingTuesday That You Can Still Donate to Today

After the Black Friday and Cyber Monday dust had settled, Americans rallied on Tuesday to celebrate Giving Tuesday, an annual day of generosity and giving back. Celebrities and non-celebrities alike supported the charities of their choice with donations both big and small.

Southern sweetheart Reese Witherspoon lent a hand to Girl's Inc. in Tennessee and stopped to take a photo with a group of young girls the organization is working to empower and inspire. "While in #Nashville, I had the great opportunity to meet these amazing young women and talk to them about financial planning and setting goals. I see bright futures ahead!" the actress captioned the snap (above), which she posted on Instagram.

And she wasn't the only celebrity using her clout to raise both money and awareness for worthy organizations: Scroll down to see the causes celebrities chose to support via social media on #GivingTuesday.
