Volcano | Vinnie Jones
The first character to be unmasked was Volcano, who performed an explosive cover of I'm Gonna Be (500 Miles) by The Proclaimers.
Despite Dannii guessing Sacha Baron Cohen, Hughesy suggesting Christian Bale, Urzila taking a stab at Billy Bob Thornton and Jackie O guessing Anthony Mundine, the judges were all incorrect on this one.
The Volcano was English-Welsh actor and former professional footballer, Vinnie Jones. He played for Wimbledon, Leeds United, Sheffield United, Chelsea and Queens Park Rangers.
As far as his acting career goes, Vinnie has had roles in Snatch, Gone in 60 Seconds, X-Men: The Last Stand, She's The Man and more.
Duster | George Calombaris
The second character to be unmasked was Duster.
After getting jiggy to Duster's cover of Shake Your Tail by Ray Charles, Dannii guessed that cricketer Shane Warne was hiding under the costume. Hughesy guessed Michael Clarke, Jackie put her bets on English chef Gordon Ramsey and Urzila suggested Indian cricketer Sachin Tendulkar.
None, however, hit the nail on the head as former MasterChef judge George Calombaris took off his mask.
George documented the experience on his Instagram, explaining that the show "pushed (him) out of (his) comfort zone" but he wanted to do it for his kids.
