Lennox took to Twitter to announce the auction, encouraging her followers to bid on items.

The Circle also discussed the exciting auction on their Twitter account. Lennox founded the women empowerment charity in 2008. Their website states the charity's goals as:

"The Circle is inspired by the notion that when women come together and organize, they can be a powerful force for change. We are a network of women from all walks of life and all backgrounds who have something in common: the awareness that we still do not live in a world where women and girls have equal rights and equal opportunities."

All funds from the auction will go straight to The Circle's "The Women and Girls Solidarity Fund," which provides safe housing for women and girls along with hygiene packages.

Bidders can bid on private performances from artists like Hozier, who also promoted the campaign through Twitter. Other items being auctioned include a silk dress worn by Lennox, a signed guitar from Taylor Swift, and a signed outfit worn by Madison Beer for her "Good in Goodbye" video shoot.
