"We respect Jamie Lynn's decision to take responsibility in this sensitive and personal situation. We know this is a very difficult time for her and her family, and our primary concern right now is for Jamie Lynn's well being," says the network, which carries her series Zoey 101.
A rep for Spears was not immediately available for comment.
The network statement follows Internet reports that Spears's mother had confirmed the pregnancy to OK! magazine.
Spears, a high school junior who is 10 years younger than Britney, had until now escaped much of the attention about her personal life that has surrounded her sister.
Jamie Lynn stars as a schoolgirl at the fictitious Pacific Coast Academy in Zoey 101, finishing its third season next month as one of Nickelodeon's highest-rated shows.
She recently told the Associated Press that didn't have a serious boyfriend.
"I kind of just keep my options open," she said. "I have a bunch of friends that I always hang out with, a bunch of guy friends."
She added that her priority was to focus on her real-life schoolwork before considering any additional TV series or film roles.
"I'm going to try to graduate before I do anything else," she told AP.
What an IDIOT. I swear, she's never gonna learn is she? Lindsay Hohan, er, I mean Lohan got busted again just 2 weeks outta rehab for drunk driving. Here's the mugshot and the full story:
Incarceration isn't pretty. Just ask Paris Hilton. She went through hell. No iPod. No cell phone (unless the head of the guards brought her one, as has been alleged). No pricey moisturizers, no little dog, no VIP section. It's just time in a cell, watching the clock tick, watching the calendar leaves flip.
Yet in her case, prison was punishment. In Lindsay Lohan's, it might be just what the doctor ordered.
Early on Tuesday morning, Lohan was arrested again, this time in Santa Monica, Calif. Police were called because they got a report that her car was chasing another. She failed a sobriety test, and cops also found cocaine on her. She was booked on two misdemeanor charges of driving under the influence and with a suspended license, as well as two felony charges of possession of cocaine and transport of a narcotic.
...until tomorrow because of the bad weather this morning. I know this sucks, and the tickets DO say rain or shine, but I was up about 8:30 this morning and it was TORRENTIAL DOWNPOUR out there! They couldn't even set up the stages :(
All you need to do is hold on to your ticket, and the show will be at the same time inside Relient Arena tomorrow. Oh, and tell your bosses that you came down with a really bad 24 hour flu and you can't come into the office.
The World's Tallest man just got married and next to him, his wife looks like the world's SHORTEST woman, but she's not! He's 56 years old and his name is Bao Xishun and he's 7'9". Not only is his wife, Xia Shujuan half his age at 29, but she's only a mere 5'6". And that's not even SHORT for a girl!
If your best friend ever has a bbq/pool party at her house complete with "vodka fruit salad", DON'T eat it. It will do bad things. Be warned, this is what it looks like.
