Nonetheless, the US star stands up and pours her water over Guy as a voiceover declares She's going to fight dirty!'
While the identity of Kelly's victim is kept a secret in the promo, The Voice's host Sonia Kruger revealed that it is indeed Guy Sebastian.
'Did you see the bit in the promo when Kelly's pouring water on his [Guy's] chair? That's because he started it,' she explained on KIIS FM's Kyle And Jackie O Show.
'You don't actually see that in the promo. It's almost like, he's kind of crushing a little bit on Kelly and it's like that guy in school that wants to punch you in the arm coz he likes you.'
She continued: 'So Kelly went off to go to the bathroom or something and he poured water on her chair! Delta saw it and she went over and cleaned it.
'This is all happening in the break. And then Kelly found out and so there was this retaliation.'
'He was doing and saying a few things that I'm thinking, "You do know we're on TV right?"' she explained.
