Pop quiz, Gossip followers:
Which is falling faster: the weight of Kate Bosworth or the ratings of CBS Evening News?
While we don't have exact figures on the former (expert estimate anywhere between 17 and 48 pounds per week), we can report that Katie Couric can't be too pleased with how her program is faring.
The CBS Evening News slipped to third place last week, drawing just 7.5 million viewers. That's almost as many people as have been flashed in this Paris Hilton picture.
Such a result has landed Couric behind NBC Nightly News With Brian Williams (8.2 million) and ABC's World News With Charles Gibson (7.6 million) for the first time since Couric took the CBS anchor chair on Sept. 5.
Still, CBS pointed out that Couric's ratings are robust compared with last year, with viewership up around 22 percent.
In other words: the show doesn't suck as much as it used to. It's the opposite of Britney Spears in that regard.
