Photographers were on hand to capture the antics of the 2013 Grammy attendees because booze plus celebrities equals fun. Or in this case, photos plus the appearance of Ellen DeGeneres equals fun.
That's not to say there wasn't alcohol or schmoozing either. Because there was plenty of that too.
Whether stars were pouring out the libations, yelling in each others faces, breast gazing (much better than stargazing) or just making new friends, there was no shortage of good cheer at the Grammy awards.
