We know we shouldn't, but we just can't help it. It's a primal, uncontrollable urge that draws the eye to lady parts. There is nothing we can do to stop it.

Women need to know -- it's like blinking. We do it because our body makes us, and there's only so long you can fight the urge before it makes us do it again.

To illustrate this natural impulse, we've collected images of media-savvy men who should know how to look suave in front of the camera. Alas, they still can't help but look like gawking fools by letting photogs catch them in the midst of an eyeful.

Men Just Cant Help But Look

    Note to Matthew McConaughey: Never stare at co-star's breasts at film premiere.

    Oh Peter O'Toole, you sly 76-year-old Oscar nominated perv. (By the way, the woman is Cate Blanchett)

    Just because you're married to Kate Winslet doesn't make it okay Sam Mendes.

    We're not going to say anything offensive but you can guess what thoughts we wanted to put in Orlando Bloom's mind.

    Lucy Liu, meet Zach Helm. Zach Helm, meet Lucy Liu's breasts.

    There was one more guy in this photo but we cut him out to make producer Nigel Lythgoe look like a creep. Yes, we're being cruel.

    We're not sure why exactly Take That member Mark Owen was looking at Girls Aloud member Sarah Harding.

    Ashton Kutcher is young, wife Demi Moore is still hot. It's okay.

    It must be hard being a back up dancer for Girls Aloud -- one of the hottest girl bands on the planet.

    Despite all the hate on the show, we knew there would be something Simon Cowell liked about Paula Abdul.
