The reality star is promoting an internet campaign in which stars including Lady Gaga, Justin Timberlake and Usher will quit social networking sites to raise money for charity.
In an unusual initiative, a host of celebrities will log off and not sign back in until $1 million (£640,000) has been raised.
The Digital Life Sacrifice is being organised by Alicia Keys' Keep A Child Alive charity for World AIDS Day on Tuesday.
Jennifer Hudson, Ryan Seacrest, Elijah Wood, Serena Williams and Swizz Beatz are also taking part.
They have filmed 'last tweet and testament' videos which will appear in ads showing them in coffins to represent what the campaign calls their digital deaths.
Lady Gaga has more than seven million Twitter followers - while 3.5 million have signed up for Justin Timberlake's tweets.
World AIDS day, held December 1, is about raising awareness about AIDS caused by the spread of the HIV infection.
AIDS had killed more than 25 million people between 1981 and 2007, latest figures have revealed.
Lady Gaga: Has Seven million followers on TwitterAlica Keys is the first global ambassador the the Keep A Child Alive charity.
She said today that no celebrity had turned down her request to take part.
'Once I got people on the phone and I was able to paint the concept for them, everybody was in,' she said.
Leigh Blake, who is president and co-founder of the charity, said: 'We're trying to sort of make the remark: Why do we care so much about the death of one celebrity as opposed to millions and millions of people dying in the place that we're all from?'
Keys married rapper-producer Swizz Beatz in July.
