(Cover) - EN Showbiz - Arcade Fire found Lady Gaga's reaction to their Grammy win hilarious.

The Canadian band caused one of the biggest Grammy upsets of all time after their album, The Suburbs, saw off Gaga and Eminem's offerings to be named record of the year at this year's ceremony. They admitted they had to laugh when they saw Gaga's response on TV after the event.

"It was on time delay so we watched it back in our hotel," Win Butler told Q magazine. "We didn't go to any after-parties, we just had our own. There was this really funny shot of Lady Gaga while we're performing, sat in her big stupid hat looking so upset after we won."

Win couldn't believe the reaction from the audience following their triumph, labelling it "hilarious". The group performed at the event, and were surprised with how their songs were received.

"At the ceremony, I don't think we've ever played to a more apathetic audience in our lives," he added. "People with these horrified looks on their faces." (C) Cover Media
