The Czech model was on vacation in Thailand when the deadly tsunami struck, killing almost 280,000 people, including her fiance Simon Atlee, reported Contactmusic.
She subsequently founded the Happy Hearts Fund to help rebuild schools in areas devastated by natural disasters and she will host a gala at New York's famed Cipriani restaurant on June 19 to boost donations.
Crow has now agreed to perform at the benefit, alongside Black Eyed Peas rapper apl.De.Ap, who will also be honoured for his charity work.
"My deepest gratitude goes to everyone who has supported us over the last few years and has helped us create a bigger and more powerful wave than the Tsunami did - a wave of hope, empowerment, opportunities and brighter future," she said.
The beauty has already helped to rebuild 85 schools around the world via her Happy Hearts Fund.
