Grammy Award-winning singer Amy Winehouse, who has made headlines more for her drug battles, rocky relationships and legal woes than for her acclaimed music, has vowed that her much-anticipated next album is just months away.

"The album will be six months at the most," she told the U.K.'s Metro news daily on Tuesday night, while attending the London premiere of the film Psychosis, by her new boyfriend, writer-director Reg Traviss.

"It's going to be very much the same as my second album, where there's a lot of jukebox stuff and songs that are — just jukebox, really … I just can't wait to have new songs on stage."

Winehouse's second album, 2006's retro-styled Back in Black, was an international sensation that garnered the singer a raft of awards, including a hefty five trophies at the 2008 Grammy Awards (for best new artist, best pop vocal album and record of the year, song of the year and best solo female vocal performance for the infectious single Rehab).

She turned in her Grammy performance via satellite from London, after her U.S. visa request was denied.

Even as her star was rising with the release of Back in Black, her personal life was spiralling into chaos — filled with erratic behaviour, multiple stints at drug rehabilitation clinics, shambolic performances, assault lawsuits and a turbulent, short-lived marriage.

Surprise guest

The singer's declaration of a forthcoming new release is dramatically different from the most recent update from her producer, Mark Ronson, who also produced Back in Black.

The British hitmaker told reporters that Winehouse "hasn't begun working on her next record yet" following a performance at London's 100 Club last week to launch his new band, The Business Intl.

"When she's got 10 songs, we'll go down to the studio together," he said.

Winehouse, who had turned up as a surprise guest at Ronson's gig, joined him onstage for Valerie, the track she sang on his previous album Versions.

However, the performance was rocky, with Winehouse appearing to forget the lyrics. She later said that she had been unsure which version of the song they were to be performing.

Island, her record label, had said last fall that a new record would be forthcoming in 2010.
