Karl is currently on his honeymoon in Aspen with new wife Jasmine Yarbrough.
On Thursday, the TODAY show's entertainment guru Richard Wilkins gave an emotional tribute to his colleague.
“Karl Stefanovic has been a co-host of this great show for 14 years and I’ve had the honour and pleasure, and pressure, sometimes of working alongside him almost every day over that time, and I can tell you from the heart that there is nobody who has worked harder for this show than Karl,” Wilkins said.
“He is a fantastic, intuitive and intelligent journalist. I describe him as an intoxicating mix of world’s best broadcaster and naughty schoolboy.
“There is no secret that the past year or so has been difficult times for Karl but I can say he has walked into the studio every morning with energy and passion bringing ideas to make the show bigger and better.
