REDLANDS, Calif. -

A former Southern California teacher who allegedly gave birth to her student's baby has pleaded not guilty to having sex with three underage boys.

The Riverside Press-Enterprise says 28-year-old Laura Whitehurst entered the pleas Tuesday to 41 felony counts. She remains jailed and could face up to 29 years in prison if convicted.

Whitehurst is a former teacher at Citrus Valley High School in Redlands. Prosecutors contend that she began a sexual affair with a student last summer when he was 16. She gave birth last month.

She's also accused of having sex several years ago with two students, who are now adults.
