At the Oscars, ballgowns and updos reign supreme. If stars get up to carouse during the commercial breaks, you wouldn't know it. But at the Grammys, outré fashion and unlikely mingling are key. We bet Lady Gaga isn't going to arrive at the Oscars in a giant egg later this month, but she sure did at the Grammys in 2011.
Days before we find out what threads disgust your grandparents this year, it's our duty to explore the past two decades' Grammy-inspired joie de vivre. Each of the photos below is a "caption this" moment, because when else do we witness the reunion of "Divas Live '99" headliners Tina Turner and Cher?
Here are scenes from the past 20 years' awards. Most take place at the ceremony, while a few hail from the annual weekend's illustrious bashes. Below each photo you'll find the big winners from that year, because it's important to remember that Evanescence and Duffy (who?) are top-tier Grammy champs.
