These stars said no to 'DWTS'

Under the heading, "What's the Worst They Can Do? SAY NO?," here are just a few of the people "Dancing With the Stars" approached to appear on the upcoming season. The Hollywood Reporter uncovered this list Wednesday:

Sylvester Stallone. Sly is hot again thanks to "The Expendables," which probably is why he declined.

Ann Coulter. Like Cloris Leachman, would add element of danger.

Mark Zuckerberg. Facebook founder counters sociopath nerd portrayal in "The Social Network" with cool new fleetfoot image.

Condoleezza Rice. If former House Republican leader Tom DeLay could do this, why not Condi?

Erin Brockovich. Activist with household name status.

Richard Branson. Virgin Airways founder never met a challenge he couldn't beat.
