Karl Stefanovic takes a swipe at Allison Langdon and his former co-hosts live on Today

Today host Karl Stefanovic took a cheeky dig at co-anchor Allison Langdon and his former colleagues live on the Nine breakfast show on Wednesday.

The 46-year-old took the swipe after watching a Tim’s Trivia segment, in which weatherman Tim Davies quizzed viewers on their general knowledge.

A viewer named Steve was asked to name Karl’s co-host, which he got right.  

‘I do love that Leaning Tower of Pisa [answer],’ Karl said with a laugh, after Steve said the tower was in Paris.

‘I wouldn’t have got the first question right, today’s date!’ Ally said. 

Karl also said he wouldn’t have known ‘any of those answers’.

Ally then asked him: ‘Do you know your co-host?’  

‘Nope… hard to keep up with!’ Karl joked back, which prompted Ally to respond: ‘We’ll see who it is tomorrow.’

He was seemingly referring to the revolving door of co-hosts on the Today show in recent years.  

Karl and Ally made their debut as co-hosts earlier than expected in January last year, as they covered the Australian bushfire crisis at the time.   

Karl was famously fired from the program in December 2018, after 14 years of hosting the long-running TV show.  

Shortly afterwards, it was announced Deb Knight and Georgie Gardner would be assuming the roles of hosts of the breakfast TV show.

But their run was short-lived, with the series plummeting to some of its lowest ratings on record.

It was then announced Deb and Georgie would be departing the program, with Karl returning once again alongside Allison.  

Before co-hosting with Ally, Karl was also in the chair alongside Lisa Wilkinson. 

The pair co-hosted the show together for ten years. 

But she left Nine in October 2017 over a reported gender pay gap dispute.
