An Oakdale high school senior is being prevented from bringing his chosen date -- a porn actress -- to prom.

Mike Stone tweeted one member after another in that profession, seeking someone willing to go to the Tartan High School prom at Landmark Center in St. Paul.

Megan Piper said on her Twitter account that she'd love to accompany the 18-year-old to his rite of passage May 12 as long as Stone paid for her transportation from California.

Patty Phillips, superintendent of District 622, said Wednesday in a written statement that Piper would be unwelcome. "This prom date will not be allowed to attend the Tartan prom as her attendance would be prohibited under Tartan's standard prom procedures and would be inconsistent with two school district policies," one covering visitors and the other addressing school-sponsored student activities.

The visitor policy reads, in part, that access is allowed unless "the visit is not in the best interest of students, employees or the school district."

The activities policy prohibits, among other things, any act that "substantially disrupts the orderly operation of school or school activities."

Jennifer McNeil, spokeswoman for the North St. Paul-Maplewood-Oakdale School District, said that prom procedures require that all dance guests have their names submitted and cleared by school officials before attending.

Stone and Piper did not immediately respond to requests seeking comment.

McNeil said that Stone is not in any trouble at school for his unorthodox approach to getting a prom date.
