Me three!
Pierre Elliot Trudeau (back in the day), and his sons Sacha and Justin are all pretty swoon-worthy. Maybe Ben Mulroney at a stretch. 
Actually, Prince Harry may be further from succession and not quite as GQ but he’s nothing to sneeze at either. Thank God that Diana’s genes won both those little wars of conception.
Well, if authors don’t count as entertainers, then Peter Matthiessen all the way.
What about NPR? I’ve recently developed a crush on Jad Abumrad. Didn’t even know what he looked like till I was searching for this thread. I just really love his voice. Oooh, and Brian Lehrer.
And for a nerd crush, I give you the sociolinguist Allan Bell. I met him at a conference, and made a total ass of myself when he complimented me on my paper.
She can analyze my rivets anytime!
Max Kellerman. I never follow what he’s talking about, but he’s nice to watch.
5-4, you are a scandal! 
However, I certainly hope it’s not a corn cob… fans self
Good choice!
How 'bout Samantha Power?
Psssssst, rumor has it that he is as gay as a picnic basket.
NTTIAWWT.
Since the OP didn’t mention authors, I’m going with John Irving & Andrew Vachss. And Cecil Adams.
I just have to throwAlina Kabaeva into the fold.
She´s a politician now, so she should count, right?
So … “rhythmical gymnast”? Is that what the kids are calling it these days?
Oh yeah, that’s pretty commonly known.
I know and I’m sorry.
However, as I just caught(for the first time) the Jeopardy replays of her run last week and since no one answered you the first time around, I just had to chime in to say that yes, yes she does; very much so. Wow.
I kind of had a feeling I would find at least one mention of her here, but I just couldn’t let it go unnoted.
I’ve got toss in Charlotte Casiraghi and of course Maria Sharapova.
The cute little girl down at the farmer’s market. She is young enough to be my daughter, I’m sure, but she is so cute and perky, she is always friendly, she just makes me smile.
Local newscasters? I’ll mention Laura Borchers in Cincinnati:

And that isn’t a very good picture, either.
This report on hot playgrounds is better:
The bartender at my local pub. Joe is adorable. Sorry no pic.
Well, that didn’t work! Try this:
I’ve always been fond of NPR’s Ira Flatow. He can talk science to me any Friday. 
Ms. Madigan is a friend of my stepkids’ family…OK, that sounds weird. Their great-uncle shared an office with her at the Illinois State Legislature. Very friendly in person, my wife says.
