Last week, Jamie Lynn Spears, star of “Zoey 101″ on Nickelodeon and younger sister of Britney Spears, caught the eye of the public when she announced she was 12 weeks pregnant.

Some may wonder how the actions of Jamie Lynn Spears and other young celebrities are affecting today’s children and teenagers.

“(Jamie Lynn) is showing other teenagers that it’s OK, when it’s not,” said Natalie Serna of Jamie Lynn’s pregnancy.

The La Quinta High School sophomore is one year younger than 16-year-old Jamie Lynn.

“She’s going to be just like her sister. That’s bad,” Natalie said.

Britney Spears has been making headlines for years with her marriages and children. In February she shaved her head and later signed herself in to a rehabilitation clinic. Later, throughout 2007, she made more news with her custody hearings with ex-husband, Kevin Federline.

According to Marc Daltry, a Mt. San Jacinto junior in Cathedral City, today’s celebrity role models are not worth looking up to.

“They’ve all been arrested and they got their kids taken away,” Marc, 16, said.

Jamie Lynn and Britney Spears’ mom, Lynne Spears, had been working on a book - “Pop Culture Mom: A Real Story of Fame and Family in a Tabloid World.”

A few days after Jamie Lynn’s announcement, Lynne Spears’ publisher’s spokeswoman announced the book was delayed indefinitely.

Before Jamie Lynne, Paris Hilton earlier this year had another clash with the media for going to jail for a probation offense.

Lindsay Lohan made news for her behavior during the filming of “Georgia Rule” and ultimately returned to a substance abuse rehabilitation facility.

About two weeks before the end of the year, Jamie Lynn announced her pregnancy to the world through an interview with the British magazine, OK!

The father is her boyfriend, Casey Aldridge, she told the magazine.

With children seeing Jamie Lynn as a role model, some parents may wonder what kind of advice to give their children about teen pregnancy.

“Many teen pregnancies could be prevented if we just concentrated on teen sex education at home and in schools,” said Rory Goshorn, a marriage family therapist who works out of Palm Springs.

“Parents should have open and honest communication with their teens about sex education,” Goshorn said.

A teacher at Palm Desert Middle School, Ginny Foster agreed.

“We discussed anything and everything,” Foster said of her and her parents.

“There was not an off-limit subject,” she said. “I could talk to them about anything.”

Goshorn also said it’s important to have services in place for teenagers who do become pregnant.

“Many teens lose the support of their family when they need it most, and without community programs for teen pregnancy, these girls would have nowhere to go,” he said.
