Karl Stefanovic was living it up in Las Vegas with wife Jasmine on Thursday.

The Today breakfast show host, 50, sported a huge grin as he was took a video of himself bursting out into song in the middle of a street in the US.

Uploading the clip to Instagram, the media personality belted out the chorus for Here I Go Again by Whitesnake alongside a local busker.

His partner Jasmine, 41, could be seen laughing at her famous husband’s antics before quickly ducking out of frame when he turned the camera to her.

‘Vegas—everyone together now,’ Karl captioned the video.

He then tagged the NRL as he appeared to be attending the NRL Las Vegas Nines Tournament.

It comes after Karl put rumours to rest about any likelihood of Samantha Armytage taking Sarah Abo’s hosting seat beside him on Today.

The TV veteran told Stellar magazine he would sooner retire from helming the flagship breakfast program than work alongside another new co-host.

‘I don’t see Sarah ever being replaced. And I genuinely have no interest in working with anyone else,’ he said earlier this month in the wide-ranging interview.

Channel Nine was reportedly plunged into back-to-back crisis meetings in December, following the decision to bring Sam, 48, onto the Today show as a summer fill-in co-host.

The network’s move sparked outrage among long-time staff, with insiders alleging the decision created tension behind the scenes and left many feeling snubbed.

Sarah, 39, replaced longtime host Ally Langdon on Today in January 2023, and according to Karl, he has no interest in partaking in any further hosting re-brands.

Karl has been with the breakfast show for 20 years and in that time has seen many co-hosts—including Tracy Grimshaw, Jessica Rowe, and Lisa Wilkinson—come and go.

‘In this game, there’s stuff you have control of and there’s stuff you don’t. At any point on any given day, I can be replaced. The show is bigger than I am,’ he said.

‘That’s not a slight on Sam. I’ve done 20 years, and I don’t know about going through all that with another person. I’m closer to the end than the start. That’s the reality.’

All eyes were on the defected Channel Seven star over the summer holidays, as Sam warmed up the hosting seat for a two-week fill-in stint alongside weatherman Dan Astley.

‘There have been crisis meetings back-to-back since Sam was signed,’ a source told Woman’s Day in December.

A well-placed insider told Daily Mail Australia that Nine had a strategic reasoning behind Sam’s appointment.

‘Let’s not pretend this isn’t about ratings,’ they said.

‘If Sam manages to pull Today out of the shadow of Sunrise, even for a week, the network will see it as a win. For Sam, it’s about proving she’s still the queen of breakfast TV.’

If the motivation was to test the ratings waters for Sam, though, results were tepid at best.

According to the OzTam ratings, most viewers were still tuning into Sunrise—Sam’s old stomping ground—during her fill-in stint on Today.

Meanwhile, new kid on the block David Woiwod has been co-hosting with Monique Wright and on December 18 pulled in 979,000 total viewers to Today’s 754,000.

The dynamic duo extended their lead the following day, claiming victory with 980,000 viewers to just 749,000.

‘Everyone was talking about Sam being on Today… but no one was watching,’ a well-placed source told Inside Mail that week.

‘Meanwhile, the ratings for [Sunrise hosts] Woiwod and Mon have been amazing. It shows people are ready for something fun and new. Sam’s very much yesterday’s hero.’

‘It’s all been a bit of a trainwreck, all the publicity and dramas that they’ve cooked up around Sam, and yet people genuinely just aren’t that interested,’ a Sunrise staffer added.

Sarah was recruited to 60 Minutes in 2019, bucking the trend of internal appointments to Nine’s coveted breakfast show.

She moved from  Melbourne to Adelaide, back to Melbourne, and then Sydney, from Ten to SBS to Nine—to establish her name and reputation to score the hosting gig alongside Karl.

Karl described himself as ‘so fortunate’ to be working alongside her.
