British soul singer Amy Winehouse has married her on-off boyfriend, Blake Fielder-Civil, in Florida, her representatives confirmed on Monday.

"Amy did indeed get married to fiancee Blake Fielder-Civil on Friday, May 18, in Miami, Florida," her spokeswoman Tamara Lamb told Reuters in an e-mail.

Last week the singer denied any wedding plans and said her trip to Florida with six friends was just a holiday. She got engaged in April.

Winehouse, 23, won the best British female solo artist award this year at the Brit Awards, the UK music industry's biggest night of the year, where she performed her hit single "Rehab," about her refusal to get treatment for alcohol dependency.

The London-born singer has earned herself a reputation for her drunken antics on and off stage but recently was quoted as telling reporters that she had vowed to her boyfriend's mother that she would clean up her act.

The singer burst on the scene with her first album, "Frank," in 2003 and won an Ivor Novello Award in 2004 for her debut single "Stronger than Me." Her second album, "Back to Black," was released last year and went to No. 1 on the British charts.
