Just because Nick Lachey and Vanessa Minnillo didn't get married last weekend doesn't mean they can't party like it's their reception!

X17 photogs spotted the as-yet-unhitched duo with a box full o' booze Monday afternoon, and we couldn't help posing the question of their future together.

Although they tried to keep stone-faced while our earnest photog asked them about whether marriage or children were in their near future, Nick and Vanessa couldn't help but giggle conspiratorially once they got into the car!
