Catholic School Teacher Accused of Abusing 2 Boys Compared To Sabrina Carpenter Music Video

A former Catholic school teacher is accused of sexually abusing two teenage boys nearly 40 years ago ... with one claiming she behaved like she was "in a Sabrina Carpenter video."

Sally-Anne Bowen, now 65, was in her mid-20s while teaching chemistry at an all-boys Catholic school in North London ... and she allegedly had sex with one boy 20 to 30 times when he was 14 or 15, according to The Telegraph.

The accuser was referring to Carpenter's controversial "Feather" music video ... which featured the pop star dancing inside a Brooklyn Catholic church and sparked outrage from church officials.

The former student says the alleged encounters took place over several months, including at her home, and he believed she was his girlfriend.

A second accuser claims he kissed Bowen at a café and touched her breasts.

Bowen denied the allegations Monday ... calling them a "total fabrication" and "the workings of a fantasy." She also rejected claims she wore tight tops and miniskirts at school ... insisting her skirts stopped a few inches above her knees.

Her explanation ... "I wasn't going to dress like Margaret Thatcher."

Bowen also denied discussing sexual positions with students and insisted she never crossed professional lines.
