Well even if you're not a celeb, we've got some hot picks for geek glasses so you can try this trend on for size.  And just so you know, you're not alone - there's even a Facebook fan page for big, nerdy glasses.

Justin Timberlake

I don't think Justin could ever look anything but...hot, sexy and did I say hot? Even when he's trying to look stylishly geeky, he's bringing sexy nerd back.

So if you want your man to slip on something a little sexier and more stylish, a la Justin Timberlake style, than try these Wayfarer Geek-Chic designer fashion reading glasses for youthful men who read in style from Ritzy Readers, sold at Amazon, $26.99.

I mean, if he ain't got what JT got, you can always take them off, right?

Madonna

Oh Madge, how I've loved watching you grow old. Well, not really. I mean, you look the same as you did when I was in high school scrunching my hair, wearing a big lacey headband and shouting "Borderline" into my hairbrush. How do you stay so youthful?

Perhaps it's the way you are not afraid of even the most out there trends - and these geeky classes make you look as youthful as ever. If you like Madonna's version of nerd, look no further than these black plastic framed nerd glasses from Hot Topic, $9.99. Come on, I dare you.
