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

Fowlkes, 26, was suspended from her job as an anatomy and physiology teacher at Lockhart High School after turning herself in to police Monday – hours after celebrating her birthday with her hubby.

The beaming blonde allegedly engaged in “sexual content with the intent to arouse or gratify the sexual desire” of the student, the Daily Star reported.
