Bristol Palin abstinence talk cancelled

A Bristol Palin university speaking engagement has been cancelled.

Washington University in St. Louis and the star both agreed to drop the speech after "growing controversy among undergraduates over the decision to pay for [the] talk with student-generated funds", said a rep for the school.

According to TMZ, Palin was booked to speak about abstinence and teen pregnancy next month.

The 20-year-old daughter of Sarah Palin became a mother at the age of 18 and works as a paid speaker on the subject of teen pregnancy.
