The mum-of-one posed for the cover of US magazine Savoy to promote the album - a re-built version of the mega-hit original from 2001.
Exposing her washboard stomach while sporting a long leather coat and floppy hat, Keys told the mag: “This album is possibly the most precious to me. Your first album only happens once so Songs in A Minor will always hold a special place in my life.”
The original album sold over 12 million copies worldwide and earned Keys five of her 14 Grammys.
The collectors' edition record includes previously unheard songs as well as re-mastered and re-mixed versions of the old tracks.
'I'm so proud that the songs are still being enjoyed around the world,' said the New York singer.
Keys, 30, is married to the record producer and rapper Swizz Beatz, 33.
On October 14, 2010, she gave birth to their first child, Daoud Ibarr Dean, in New York.
