Last month Hannah Wackernagle posted a touching “promposal” video to YouTube asking Dancing With The Stars’ James Maslow if he would do her the honor and be her date.The Big Time Rush singer couldn’t fly to Ohio for her big night, but he decided to give her another moment to last a lifetime as his date on Dancing With The Stars where Hannah got her own private prom. Maslow flew Hannah, her mother Hollie and little sister Lily to Los Angeles for a whirlwind weekend of dancing and Disneyland.
