You might not be a rock star, but Miley Cyrus is about to give you the chance to tour like one — at least for a day — and raid her closet while you’re at it. The teen star is partnering up with eBay in an online auction that gives one fan and three of her friends the chance to hit the road with the teen star, and be her “roadie for a day,” going behind-the-scenes at one of her upcoming concerts and hanging out backstage. Miley is also cleaning out her closet and auctioning off some of her favorite outfits — including this Theory dress that she wore to the Bolt premiere last November. All proceeds from the auctions will benefit the Pappy Cyrus Family Foundation, the Cyrus family’s personal charity that was founded last year in honor of her granddad to help kids in need. Bidding starts tomorrow Thursday August 6th and ends August 13th at 7 PM PT. Click here to learn more and get bidding!
