Singer Amy Winehouse's friends were reportedly left dumbfounded when she sniffed neat vodka shot up her nostril during a night out.
The 24-year-old singer shocked her friends Kelly Osbourne, Kimberly Stewart, Miquita Oliver and Mark Ronson while snorting up 20 shots.
"Amy was the life and soul - but even we were shocked by this party trick," Mirror quoted an insider as saying.
"She was sat next to Kelly and Miquita when she covered one nostril, tilted her head back and sucked the vodka shot down her open nostril through a straw," the insider added.
"She threw back her head and reeled in shock and everyone around her looked stunned.
"She necked the top of the shot and lit the rest with a lighter. Then she grabbed a straw and sucked what was left up her nose," said a source.
