It's official: Tom Selleck is joining the cast of NBC's "Las Vegas" next season.

He'll play a "charismatic, self-made billionaire" who becomes the new owner of the Montecito, according to NBC.

He'll also try to fill the star power vacuum created with the exit of James Caan, who'll appear only in the first episode next season.

It still has all its teeth

The Discovery Channel's "Shark Week" will mark its 20th birthday starting July 29.

Sass on the side, please

Bravo, apparently concerned that "Project Runway" mentor Tim Gunn might not have enough firepower to carry his own show - the upcoming "Tim Gunn's Guide to Style" - has hired supermodel Veronica Webb to help out, or as a Bravo exec put it, to "add a little sass to his class."

Since when does class need sassing up?
