Seb Costello departs Triple M’s Hot Breakfast a year after his bizarre feud with Edwina Bartholomew

Seb Costello has left Triple M’s Hot Breakfast. 

The journalist, who is the son of Nine chairman and former Australian Treasurer Peter Costello, made the announcement this week saying he’s leaving because he’s now joined Nine’s A Current Affair. 

The move comes a year after Seb’s bizarre feud with Sunrise’s Edwina Bartholomew, where she reportedly paid him $20,000 and offer an apology to him after posting an ‘errant tweet’ about him. 

On Instagram on Thursday, Seb wrote that he’s had an ‘amazing time’ working with Triple M over the years. 

‘As announced on air today, with my recent appointment at A Current Affair I’ve decided to wrap up my role on Triple M Melbourne with the Hot Breakfast team tomorrow.’

He added: ‘My involvement at the M’s goes back [to] 2015 and it’s been an amazing time. More reflection on air tomorrow.’

The announcement comes as hosts Eddie McGuire and Luke Darcy depart the Hot Breakfast Show. Their last show was aired on Friday. 

In October last year, Edwina Bartholomew apologised for her ‘errant tweet’ about Seb, almost six weeks after the incident took place. 

But it was also reported at the time that the Sunrise presenter did a lot more than simply issue a public apology to clear the slate with Seb. 

The Daily Telegraph claimed that the Sunrise presenter also ‘had to pay Costello about $20,000’.

Edwina publicly apologised to him via Twitter for her ‘inappropriate’ tweet about Seb.

‘On 14/9 I made a statement on Twitter about @sebcostello9. While I won’t repeat it, what I said about him was false, hurtful and completely inappropriate,’ she started off the tweet.

‘I unreservedly apologise to Seb and his family for the hurt and offence my words caused.’ 

In mid-September the then pregnant 36-year-old presenter ‘backhandedly praised’ his reporting on Twitter, according to The Herald Sun.

The tweet, which cannot be republished for legal reasons, was in response to one of Seb’s Nine News reports and stated: ‘Surprisingly articulate for a [censored].’ 

Daily Mail Australia revealed days after the incident that Edwina’s tweet was actually meant to be a private message to a friend.

The tweet in question reportedly stayed up for 50 minutes before being deleted and was in response to a Nine News Melbourne post, which has also been deleted.

The well-loved presenter, who was reporting from London at the time, confirmed she made the ‘errant tweet,’ with the Herald Sun reporting that Nine was ‘understood to be reviewing its legal options.’ 

‘I was half asleep and on the other side of the world. It was clearly a mistake and the errant tweet has been deleted,’ Edwina told the Melbourne paper.

At the time, senior management figures stood by Edwina, who were ‘sympathetic’ to her situation and vowed to ‘continue to back her 100 per cent’, according to network sources.

Seb, who is the son of Nine chairman and former Australian Treasurer Peter Costello, had addressed the Twitter scandal on Triple M’s Hot Breakfast radio show on September 17.

‘It’s not ideal what was said, I spent the weekend with family and it’s not ideal for them either,’ he said, adding that he would be talking with lawyers that week.
