The online competition will be run through a custom-built Facebook application where contestants can upload and share their dance videos for public voting.
The 10 videos with the maximum number of votes will be short-listed and Katrina will select and announce the three finalists, and then the ultimate winner on May 20.
The first prize is lunch with Katrina and $5,000 cash prize, two Pearl Business Class tickets, and accommodation in a 5-star hotel for five nights. The first runner up will receive two Pearl Business class tickets, and the second runner-up, two Coral Economy class tickets to anywhere on the Etihad network across 66 destinations.
