What was the name of that horrible show?

Are You Hot? It wasn't.

Other than that, i think he spends his time marrying blond, buxom women half his age.

They're not all that blonde. (For that matter, would everyone stop semi-randomly throwing people into my group? We have standards and it was bad enough when y'all tried to force Paula through.) According to Wikipedia, he's been married four times and broken off at least one engagement, probably because the wedding veil threw a single hair out of place. http://en.wikipedia.org/wiki/Lorenzo_Lamas if you want to review.

(Was his son on this a few seasons ago?)

If it happened, it was either before my viewing time or my memory threw the Curtain Of Mercy over the season. One of his daughters was on (and 'won') a Bachelor season, and his co-host from the above-mentioned travesty was one of the original DWTS contestants.

Who was the Baywatch stay that was on Celebrity Fit Club, but couldn't leave her white wine at home?

Both Nicole Eggert and Erika Eleniak have been on CFC: it looks like Nicole was the wine drinker.

As long as I'm posting: other current rumored participants are Phil Hellmuth (is tweeting his own possibilities), Julie Benz (Tom wants her for the show, she's willing to oblige, and there's an ABC link to boost her odds) and Portia de Rossi (love to see if the show has the courage to put her with a female partner, but already know the answer).
