Simon Cowell says he's learned one lesson from the U.S. launch of his TV show "The X Factor". To keep his big mouth shut.

That means he is not commenting on speculation that music stars such as Britney Spears, Janet Jackson and Black Eyed Peas singer Fergie might become judges when the revamped TV singing show returns to Fox television in September.

Nor is Cowell falling into his own trap again and planning on forecasting the size of the TV audience for the second season -- except to say it will be bigger than last year's 13 million average viewers, which was far below his pre-season boasts. About The Author: Steven Rogers
