Bristol Palin won't be speaking to Washington University students about teen pregnancy and abstinence. Student protests caused the university to withdraw their invitation to Bristol, Reuters reports.

The University Student Health Advisory Committee proposed the appearance as part of Student Sexual Responsibility Week and approved of spending $20,000 to sponsor the panel which would feature the 'Dancing with the Stars' alum.

But "because of the growing controversy among undergraduates over the decision to pay for the talk with student-generated funds" the committee decided it was best to cancel the abstinence advocate's appearance.

Bristol became pregnant at 17, and at 20, is now a single mom to her 2-year-old son Tripp. She's "thrilled" with her new life in Arizona, and even has a new boyfriend. Although she wasn't an abstinence practitioner during her own teenage years, she's now an outspoken advocate for waiting until marriage to have sex.
