Holy Hilton?

Paris may have spent the weekend in Vegas - but yesterday, we caught her going to church!

Granted, the hotel heiress wasn't stopping by to worship; the whole Hilton family was attending a graduation ceremony. Still, it appeared that Paris' time in church was well spent - when we spotted her stopping by a liquor store later that evening, we didn't see her pick up anything stronger than a Stouffers microwave dinner!

(Of course, if you want to see Paris get wild, we've updated our gallery of her Vegas vacation with even more pix - check it out below!)
