If you're wondering what shoe size U.S. legend Oprah Winfrey takes, it's an Italian size 41.
Women all over the world are asking themselves this question because the talk show queen is currently auctioning off a pair of her Christian Louboutins on eBay with all proceeds going to a Melbourne charity.
With five days to go, bidding is at more than $1200 with 27 bids.
It's not the first time Oprah's given away a pair of designer shoes -- In 2012, during a speech, she reportedly took off her shoes and handed them to an audience member.
In 2010 she did a massive charity wardrobe clean out including a pair of Prada wedges.
In the 90s, a woman who bought yet another pair of Oprah's shoes at a charity auction went on to say how the purchase changed her life and inspired her to get an education.
The charity benefiting is named One Girl and every cent raised from this auction will go the Do It In A Dress campaign to help provide school dresses for girls in the impoverished African nation of Sierra Leone as well as providing schoalrships, business training and building new classrooms.
