Jackie asked the former Married At First Sight star if the potential fallout came as a result of having to ‘attack someone’ in the show’s boardroom.

‘Because I’ve notice some pap shots out and about… I’ve noticed there’s been sort of a clique form,’ Jackie ‘O’ said.

Martha responded: ‘They put you in teams but the teams are always changing so The Veronikas are my favourite. They’re like the sweetest girls.’ 

The show is set to air on Channel Nine next year and features British billionaire Lord Alan Sugar as CEO. 

Daily Mail Australia has contacted Nine for comment, in relation to this article.
