For the first time since the arrest of her husband, Blake Fielder-Civl, Amy Winehouse performed Wednesday in a controversial comeback that resulted in her storming off stage after being booed by the audience, the BBC reports.

The troubled, wobbly chanteuse dedicated her song "Wake Up Alone" to the embattled Blake Fielder-Civil, who is currently in a London prison awaiting trial on charges of witness tampering.

"This is for my husband," Amy Winehouse said on stage.

As disgruntled fans headed for the exits, Amy Winehouse announced: "To them people booing, wait 'til my husband gets out of incarceration. And I mean that."

Her closing number, a cover of The Zutons' "Valerie," descended into chaos when she stopped singing, dropped the microphone and walked off stage.

"When she did sing she sounded phenomenal," one fan, Zoe Giorgio, told the BBC, "but she was not ready to be on stage. She was weak, so vulnerable."

The gig marked the first night of the troubled singer's 17-date U.K. tour. In August, Amy Winehouse canceled her summer shows amid reports of her own drug and alcohol abuse. She and Blake Fielder-Civil married earlier this year.
