Blushing bride? Reluctant groom? Hardly. On June 20 Jill Peterson and Kevin Heinz literally danced down the aisle of Christ Lutheran Church in St. Paul to Chris Brown's R&B hit "Forever." Preceded by 16 boogying attendants, Heinz, 28, a law student, somersaulted into the sanctuary. By the time psychology grad student Peterson, 28, clad in a silk Nicole Miller gown, gyrated toward her intended, guests were on their feet cheering. Says the groom's cousin Richelle Johnson: "I thought, 'Oh yeah, that's Kevin and Jill.' I was expecting something fun and it didn't disappoint." Then, via YouTube, the world got a window on two people in love. (Not seen: Heinz's grandma Margaret McCloskey, 93, rocking out to the recessional "Joy to the World," and Hula Hoops at the reception.) "My son said there might be dancing, but I had no idea it'd be anything like that," says McCloskey. "Happiness was felt throughout the whole area."
