Amy Winehouse will make a surprise appearance at the BRIT Awards in London tomorrow (February 20th), organisers have confirmed.

The performance will be the singer’s first appearance on British television since she left a London rehab clinic two weeks ago.

"I heard her rehearse last night and she sounded absolutely great," Ged Doherty, chairman of the BRIT Awards, told Sky News.

"We are just thrilled to have her appearing at the ceremony. At times it has been a difficult year for Amy but what has never been in doubt is that she is a real talent.”

Doherty said that he believes Winehouse’s performance will be one of those “BRIT ‘moments’”.

Despite her ongoing troubles, Winehouse picked up four Grammy Awards, including the prestigious Song Of The Year, last week.

Although she was not able to attend the ceremony in Los Angeles, Winehouse accepted the awards via a live video link from London.

Tomorrow's BRIT Awards will be broadcast live from Earls Court on ITV1.
