The 'Descendants' actor is obsessed with having fresh footwear and so after he has worn a pair he gets rid of them.
However, charitable George doesn't throw them away and instead has them washed and then donates them to a homeless shelter.
A source told the new US issue of OK magazine: "George has his dirty socks washed and then donates them to a homeless shelter. He just has a thing about wearing the same pair twice."
George - who is dating former WWE wrestler Stacey Keibler - is not the only celebrity obsessed with clothes.
However, not all stars want to get rid of their garments.
Singer-and-actress Vanessa Paradis finds comfort in her clothes and she finds it hard to get rid of items, even when they start to suffer damage.
She previously said: "I love to be comforted by clothes.
Obviously you want to look in the mirror and like what you see but I need to love what I feel. I need to feel comfortable in terms of sensation. I keep everything. It's not a good thing because you drown under your closet, but some things are really important to me, especially the stage clothes."
