LONDON, England (CNN) -- Amy Winehouse will sing live at the Brit Awards in her first public performance since she left a rehab clinic two weeks ago.
British singer Amy Winehouse performs last week via video link for the 50th Grammy Awards ceremony
The troubled singer will perform at the UK music industry's biggest night Wednesday.
Winehouse, 24, sang last week at a private satellite-linked performance for the U.S. Grammy awards, where she won a record five awards.
She is expected to sing two songs at the Brits, including the hit Zuton's single "Valerie," with producer Mark Ronson.
Although she is not nominated for any awards herself, her vocals feature on Ronson's reworking of "Valerie," nominated for best single.
Around 8,000 industry guests will attend the Earls Court show, hosted by Sharon and Ozzy Osbourne.
Ex-Beatle Sir Paul McCartney will perform a medley of hits after receiving an outstanding contribution award at the ceremony.
Other scheduled performers at the Brit Awards include the Kaiser Chiefs, Kylie Minogue and Rihanna.
Take That, Mika and Leona Lewis are each nominated for four awards, while Ronson, the Arctic Monkeys, Kaiser Chiefs and Kate Nash are nominated for three.
It has been a roller coaster few months for Winehouse, who went into rehab in January after the release of a home video showing the singer smoking something in a glass pipe.
The Sun, Britain's best-selling daily tabloid newspaper, made the 19-minute video public last month.
It said it was shot in Winehouse's East London home.
Her record label, Universal Music Group, released a written statement at the time saying: "Amy decided to enter the facility today after talks with her record label, management, family and doctors.
"She has come to understand that she requires specialist treatment to continue her ongoing recovery from drug addiction ... Amy entered the facility by mutual agreement and continues to receive the full support of all concerned."
Winehouse has become famous for her battles with addiction. Her hit song "Rehab" describes her reluctance to enter a rehabilitation center.
She previously entered rehab last summer.
In October, Winehouse and her husband, Blake Fielder-Civil, were arrested at a Norwegian hotel for marijuana possession, and soon afterward fans booed her on stage as she slurred and stumbled her way through her gigs.
In December, tabloids published pictures of Winehouse with a mystery white powder in her nose.
She was also photographed wandering barefoot on a London street, wearing only jeans and a bra and appearing disoriented.
Fielder-Civil is behind bars in London on charges of perverting the course of justice after a bar fight. E-mail to a friend
