The announcement that Jamie Lynn Spears is pregnant has proved good news for bosses at TV network Nickelodeon - more than double the normal number of viewers tuned in to watch the season finale of her show ZOEY 101. The fourth series of the children's programme was reportedly under threat after news broke last month (Dec07) that 16-year-old Spears was expecting a baby. But 7.3 million people watched the final episode of Zoey 101's third season on Friday - over twice as many viewers as usually tune in. Nickelodeon recently confirmed it will begin transmitting the show's fourth season in February (08).
