You’d have more of a shot if:
a) she weren’t married
b) you knew that her first name was Debbi
Do writers count as entertainment related? If not, then Neil Gaiman.
If they do, then I’ll go with string physicist Brian Greene. He’s brilliant, cute, self-effacing, plus I’ve always had kind of a weakness for Jewish guys (and English guys— Gaiman’s an English Jew, but straight alas; not sure which team Greene bats for and it’s not likely to be relevant).
Back in the day I had a thing for George Stephanopolous but it went the way of the dodo. Also had the requisite Anderson Cooper crush but it ended due to 1) the fact he’s really given too much credit for the Katrina moments he had years ago- his show’s only a bit less tabloid as Larry King’s half the time 2) his refusal to come out* 3) those damned restraining orders- they start to hurt my feelings after the first airport detention.
I will mention Jon Stewart just in case you count him as journalist rather than as entertainment, though. 
*I know I know, it’s his business and the other guys I mentioned are either straight or don’t speak to the issue, but I agree with the logic by one gay blogger- that if a guy earning $20 million per year and at the top of his game professionally is seemingly afraid to come out then what message does that send to the 16 year old in Dubuque or Scranton or Monticello, Georgia who’s struggling with gay identity? And the fact he hides it under “I think journalists should not discuss their private lives to maintain objectivity” crap when he’s written a (strangely asexual) memoir about his life and his family and coping with grief over his brother’s suicide just makes it all the more insulting.
Ok…I couldn’t think of anybody on my own…but she’ll do.
Am I insane, or could this thread not been taken seriously without a mention of Maureen Dowd? Aside from the physical, I’ve always thought of her as one of the celebrities most likely to be a closet Doper—which ratchets the attractiveness up to 11.
(Sorry if it’s not the best pic, just one of the first I found. You’re very welcome (and encouraged) to post a better one 
)
Does the new brainy phenom Larissa Kelly count?
Janet Reno
If Sampiro can have a writer and physicist, I want a cartoonist.
I find Boondocks creator, Aaron McGruder very attactive in a funny looking-cute way, made even more so 'cause I know he’s smart and fun to spend time with.
It’s her dance moves, isn’t it? 
Tiny little crush on Alison Starling, local TV newscaster.
Hmm. Having never seen a picture of him, I was expecting someone with dreads and thick Malcolm X glasses and in a T-shirt/jeans (basically Riley grown up). Never would have pegged him as a nice looking well groomed sharp dresser.
(Total hijack: I hope it doesn’t make me racist, but Ruckus is the funniest damned character on TV in years; when he said he loved being around white people because “they smell like lemon juice and Pledge furniture cleaner and is just a joy to be around” I couldn’t breathe for about 2 minutes and missed that much of the episode.)
She can storm my compound anytime she wants.
a) Oops, “World According to Garp” flashback,
b) I didn’t know they had to be single.
Depending on how we’re counting news people and whether or not certain shows count as news, strictly speaking, I have to admit I’d take on Keith Olbermann, Jon Stewart and Stephen Colbert in any combination. With plenty of brains and looks, they’re a trifecta… Olbermann is a sneaker, though, because he looks so stuffy but definitely has a sense of humor. Plus I get moist whenever he chews up Dubya–it’s that sneer of disdain and the sesquipedalianism that is proving to be a lethal combination.
I’d tear up Scott Kleeb, who’s running for US Senator in Nebraska. Mm-mm, corn fed goodness! Sure knows how to rock the ten gallon hat, too.
“Me too!” for Gaiman and Prince William.
Oh, and if writers are allowed, then I gotta say Eric Jerome Dickey is quite swoony aside from his writing, which is also fabulous.
Aaron has at times been a bit scruffier and, ahhh, revolutionary.
That is some nice, snarky goodness. When asked for second go-round though, he might say, “Mmmmmmmmmm-bushed!”
Is that a corncob in his pocket or is he just happy to see you?
I’ll be in my bunk…
Ok, since we’ve more or less let TV newscasters in, I submit: the lovely Anna while letting anyone not in the Chicago market know that this is NOT a good picture.
Not even close.
Yikes, it’s like they cartoonized her.
I’ll admit that I’ve got a little bit of thing for both Tera Williams and Michelle Gielan with our local Fox Affiliate.
Well, crap, if you’re gonna allow newscasters, there’s French newsreader Melissa Theuriau and then there’s the rest. She’s pretty much a celebrity by any definition though.
Being French, there are of course NSFW pics of her if one were so inclined to search for them.
Setting aside newscasters (who I agree are often hired to look pretty as much as anything else), I have a total crush on Illinois Attorney General Lisa Madigan. Not only cute, but wicked smart as well.
Heeey, I forgot about Lisa Madigan. She can bust me any time, but she has to have the glasses on.
Jennifer Hooper McCarty has to be the hottest materials scientist on the planet. She specializes in the analysis of historic materials.
Just listen to her talk about historical metals.
Full Disclosure- This was the first time I was turned on by someone talking about historical materials.
