Some of country music's most iconic female stars are donating special mementos to a worthy cause. Dolly Parton, Reba McEntire and Kacey Musgraves are all diving into their memorabilia boxes to donate autographed items to the Girls Rock Reverb Charity Auction, with the proceeds benefiting Girls Rock Camp Alliance, an organization that supports summer camps across the globe for youth who identify as female, transgender and non-conforming.

Musgraves has donated a six-rack microphone and line mixer, in addition to an autographed plastic pink flamingo; while Parton contributed an autographed copy of her Pure and Simple CD, vintage tour T-shirt and autographed DVD of her 2007 concert An Evening With Dolly Parton. McEntire is also auctioning off signed T-shirts, photos and CDs, including a copy of the Grammy-winning Sing It Now: Songs of Faith & Hope. 

Women from across a variety of genres are partaking in the cause, including acclaimed Americana singer Amanda Shires, who's donating her Walrus Audio Voyager Overdrive and vintage guitar pedal from the 1960s. Others participating include Lady Gaga, Fergie, Paramore's Hayley Williams, Charli XCX, Bonnie Tyler, Melissa Etheridge and Imogen Heap, all of whom are contributing various items such as microphones, instruments, concert tickets and meet-and-greet passes.

"My sister and I were very lucky to have inspiring resources at our fingertips and people championing us to find our passions very early in life. We need more perspectives of strong women living on through art and music, so I’m happy to support Girls Rock," Musgraves shares.

The auction launched on Thursday (May 10) and continues through Wednesday (May 16), with all of the money raised going toward the Girls Rock initiative.
