A teacher at a Dallas area school is under fire for something she did in her past that recently got the attention of students and parents.

Cristy Nicole Deweese, 21, is a first-year Spanish teacher at Yvonne A. Ewell Townview Center, a magnet school for grades 9-12.

It recently came to light that Deweese posed nude for Playboy in 2011 and was named "Co-ed of the Month."

Concerned parents came forward, worried that their kids have seen Deweese's photos and the impact it could have at the school.

"Students are looking for character, role models and what to look forward to, not something negative like that," said Perry Washington. "She's not a good role model but I've done some things in my past too," said Chanattra Long.

The Dallas Independent School District has not responded and officials say they could not comment on personnel matters.

Deweese did not violate any laws by posing nude. Media reports stated the Playboy pictures remain online.

Deweese has not issued a public statement and has not been in the classroom since students and parents found out about the pictures.
