Fowlkes, 26, was suspended from her job as an anatomy and physiology teacher at Lockhart High School hours after celebrating her birthday with her husband.

Married Texas teacher Sarah Fowlkes couldn’t wipe the smile off her face for her mugshot after being accused of having sex with a 17-year-old student, the Houston Chronicle reported.

Detectives launched the investigation on March 10 after getting a tip from a school administrator. They've found proof that the pretty teacher had a relationship with one of her students. “Their contact was of a sexual nature,” police said.

“I have very high expectations of myself as a teacher as well as of my students and I hope that this will be a formula for achievement,” Fowlkes wrote on the school's website.

“I want this to be an enjoyable year for all of my students but also a productive, challenging and encouraging year with success for everyone,” she continued.
