With an overflow A-list audience including Jessica Alba
, Kanye West
dancing in front of the stage, Amy Winehouse
wowed them during Paris Fashion Week on Friday night.
Entertaining 600 guests at the inauguration of Fendi's new Avenue Montaigne boutique, the troubled Grammy-winning singer took the stage at 11 p.m. in a beehive hairdo and black-strap Fendi dress hitched up with a brash metal belt.
"Forgive my ignorance, I don't know anything about fashion," she told the industry-heavy crowd, which also included Mary-Kate Olsen
, Ashley Olsen
, Sofia Coppola, Milla Jovovich and Jade Jagger.
Just hours after officially getting off the hook
in a perversion-of-justice case in England, Winehouse served up an audacious 40-minute performance. With horns and backup moving her along, she demonstrated a strong return to form, working through a set including "Rehab," "Valerie" and "You Know I'm No Good."
The evening, which included a dramatically lit fashion tableaux of live models, atrium cocktails and a separate concert room, was orchestrated by Fendi's design-meister Karl Lagerfeld, who selected Winehouse.
Between numbers Winehouse told the crowd, she was "really glad to be booked by Fendi because I was getting bored."
"I'm available for bookings," she joked. "If anyone wants me for a wedding or a bar mitzvah. ... Well maybe not a wedding. My music's a little too heartbreak. For a wedding, you need something meeker."
