Martha Kalifatidis looks tense in a new trailer for Celebrity Apprentice Australia

Channel Nine has offered a sneak peek into Celebrity Apprentice Australia.

The network released a new trailer of forthcoming 2021 highlights on Wednesday, including snippets of the series set to premiere next year.

In the video, Married At First Sight star Martha Kalifatidis appeared tense during a heated boardroom meeting.

The show’s host, British billionaire Lord Alan Sugar then said: ‘Enough of this chit chat, we’re here to do business.’

The 73-year-old is also seen telling one of the contestants: ‘This is just not good enough, you’re fired.’

Meanwhile, the two teams are also revealed as the contestants face Lord Sugar in the boardroom.

The Veronicas, Shaynna Blaze, Martha, Olivia Vivian, Alex Hayes and David Genat are teamed up to complete a challenge.

Camilla Franks, Michelle Bridges, Michael ‘Wippa’ Wipfli, Ross Noble, Anthony Callea and Rob Shehadie are also seen working together.

Meanwhile, Celebrity Apprentice Australia is set to return to screens in 2021 – for the first time in six years.

Martha recently revealed filming the reality series has been tumultuous, with ‘a few’ of the cast unfollowing her on Instagram.

‘It is stressful,’ the 31-year-old confessed to Kyle Sandilands and Jackie ‘O’ Henderson on KIIS FM’s Kyle and Jackie O show.

‘It is not fake, You know how reality TV usually isn’t real… that’s not the case with this show. It’s actually quite real. Completely unscripted.’

She also added that she has been unfollowed by a number of celebrities after tense boardroom meetings.

She later clarified she clashed with singer, Anthony Callea.
