It’s a sad state of affairs. There is absolutely no barrier of sexual behavior that TV network executives aren’t willing to cross in a desperate gambit for ratings. There also seems be to no sleazy line that a squeaky-clean teenage TV star or pop star won’t cross to "break out" into grown-up stardom.

Both of these maxims were proven again by the CW show "Gossip Girl" with a group-sex plot. Its November 9 episode depicted three friends completing a list that was supposedly printed in their college newspaper: "The 15 Things Every College Student Must Do Before Graduating." Number 11 was "Have a Threesome." And so they did.

One of the "liberated" college women in this three’s-a-crowd spectacle was actress Hilary Duff, who earned millions as a teenager as the star of "Lizzie McGuire" on the Disney Channel and in Disney movies. Millions of impressionable children idolized her. They still do – except that she’s a different kind of role model now.

Is there something in the water at NBC that gives its TV talent restless leg?

MSNBC's Chris Matthews is the latest journo to bust a move, on the March 19 "Ellen DeGeneres" show.

Looks like colleague David Gregory has some fresh competition, but I'm confident the NBC White House correspondent has what it takes. After all, he can get down to anything from Hilary Duff to Mary J. Blige.
