Animal rights activist Kesha is giving fans a once-in-a-lifetime opportunity to visit her backstage on her U.S. talent competition Rising Star and receive a style makeover as part of a charity auction. The TiK ToK hitmaker has teamed up with officials at The Humane Society of the United States to offer one lucky winner the If Only experience, which includes a one-on-one meeting with the singer, a pair of tickets to the finale of Rising Star in Los Angeles next week (24Aug14), and a personalised, autographed platinum record of one of Kesha's albums. She says, "Helping animals has always been a passion of mine and I am so proud to be able to offer my fans the opportunity to support the life-saving work of Humane Society International AND hang out with me at the Rising Star finale." Bidding for the package currently stands at $5,000 (£2,941). The sale ends on Monday afternoon (18Aug14).
