The Twins will auction off a baseball autographed by reality starlet Kim Kardashian and her ex-husband Kris Humphries. The couple signed the ball before a game last July, when the Minnesota native and NBA player Humphries threw out the ceremonial first pitch. The auction proceeds will go to the team's charity arm, the Minnesota Twins Community Fund. After a highly publicized wedding last August, the celebrity couple's marriage ended 72 days later when Kardashian filed for divorce.
