This was when Amy's musical AND personal life was under the world's spotlight.
When Amy Winehouse took to the Brits stage in 2008, she was at the height of her fame with 'Back to Black' at the top of the album charts.
Her personal life was also under the spotlight and husband Blake Fielder-Civil was serving time in prison – their destructive and substance-filled relationship had been splashed across the papers for months.
It was doubtful whether Amy would turn up to perform at all.
But she defied her critics by putting on a brave face and performing 'Valerie' in the way that only she could.
Amy performed as part of a Mark Ronson medley that started off with relative newcomer Adele, followed by Daniel Merriweather and finally Amy who stole the show.
