A source told Britain's Daily Mirror newspaper: "Amy is really excited to be asked to perform at the Grammys. It's a huge event.
The 'Rehab' singer - who pulled out of her US tour last September following a stint in rehab - plans to make a spectacular Stateside comeback by wowing the audience with a soulful medley at the Los Angeles ceremony on February 10, where she has also been nominated for six awards.
A source told Britain's Daily Mirror newspaper: "Amy is really excited to be asked to perform at the Grammys. It's a huge event.
"She's planning to do some sort of soul and Motown medley and is even weighing up the possibility of a duet with some US stars, particularly Kanye West, who has spoken in the past of wanting to work with her."
The troubled star - who also cancelled the remaining dates on her UK tour last November after a series of shambolic performances - is worried she may be refused entry to the US because of her recent arrest in connection with the investigation into her husband Blake Fielder-Civil's charge of perverting the course of justice.
The source added: "The only potential problem is that Amy will need a US visa so she is hoping her recent arrest won't cause any problems."
Amy's entry may also be affected by an outstanding drug conviction relating to her arrest and subsequent fine for possession of cannabis in Norway last year.
The 24-year-old star will launch an appeal against the conviction on February 29.
