Spears Baby Is Ratings Boost

It seems Britney Spears’ 16-year-old sister getting pregnant is a ratings winner for her kids TV show.

Zoey 101 – the Nickelodeon sitcom that stars Jamie Lynn – had its most watched episode ever last week.

The hour long season closer averaged 7.3 million viewers.

A repeat of the Zoey 101 cliffhanger on Saturday night averaged another 3.9 million.

The season finale, in which Spears' titular boarding-school teen shipped off to London, was the first new episode to air since the teenager announced she was pregnant.
