As long as they're still standing and not voted off, all the celebs on 'Dancing With the Stars' make the same amount each week (the winner makes most, naturally), so when it comes to extracurricular earning, insiders tell me Kirstie Alley is poised to profit most from this experience.

"The weight loss business is worth hundreds of millions of dollars," a friend of Kirstie's tells me. "She has already lost 70 lbs dancing and hasn't wasted one minute to capitalize on it."

The actress, who recently launched her Organic Liaison Weight Loss System, appeared on QVC a few days ago and sold out in less than 15 minutes. And she's just getting started.
