Amy Winehouse is to get round her US visa ban by singing at the Grammy Awards via satellite - and is checking out of rehab to start rehearsals.

The former Brit School student's performance will be broadcast live from a London studio on Sunday.

A spokesman for the Back To Black star said: "To prepare for the performance, Amy will be leaving the rehabilitation clinic where she has been a resident for two weeks."

He continued: "She is feeling great, looking healthy and looking forward to doing what she does best. She will remain under full medical supervision and her treatment will continue as normal."

Winehouse, 24, learned on Thursday that her visa application had been rejected.

She said: "I'm raring to go and really excited to be performing at my first Grammy Awards. I'd like to thank everyone for their support over the last couple of weeks.

"I'm really sorry I can't be there but I appreciate that I'm being given a second chance via satellite."

Winehouse, 24, checked into the Capio Nightingale clinic in north London on January 24, after a video surfaced which appeared to show her smoking crack cocaine.

She was determined to perform at the Grammys, where she is nominated for six awards.

Her nominations are Record of the Year, Song of the Year, Best Pop Female Performance, Album of the Year, Best New Artist and Best Pop Vocal Album.
