Mary Beth Haglin, aka 'Bambi' the stripper, gets charges upgraded to a ...

An Iowa teacher-turned-stripper who was charged with sleeping with a 17-year-old student is now facing tougher count after her lurid confessions during a Dr Phil appearance.

Mary Beth Haglin, 24, admitted to sleeping with the teen daily on the October 17 edition of the show. She was arrested in July last year.

As a result, prosecutors have upgraded her charges from misdemeanor sexually exploiting a minor to felony sexual exploitation - bumping her maximum sentence up from two to five years, the NY Post reported.

The pair had hooked up while Haglin was working at Washington High School in Cedar Rapids, from January to May this year - because, she told Dr Phil, he seduced her with romantic Post-Its.

At the end of class, he would leave the messages on her desk calling her ‘my empress’ and ‘Mrs Robinson’ - the latter a reference the older woman who seduces a young man in The Graduate.
