Reuters reports that E! Entertainment said Tuesday that the debut of its 'The Anna Nicole Show' "reality" show starring former Playboy Playmate and Texas oil tycoon widow Anna Nicole Smith ranked as its highest-rated program premiere ever and was also the top debut for a reality show on basic cable.

A spokeswoman said the Sunday debut of the half-hour show, which chronicles the outlandish life of the now plus-sized Smith, 34, her beloved dog Sugar Pie and her entourage, logged a 4.1 rating, which translates to over 4 million viewers.

The E! spokeswoman said the network expects the numbers to rise in coming days as final figures from Nielsen Media Research come in which will include whether one or more person per household was watching the program.
