The breakfast TV co-host shared a photo to Instagram teasing a new bald look, telling fans in the caption, “I just dropped three kilos. See ya Monday”.
While the 45-year-old looked and sounded like he might have shaved his head completely across the weekend, some fans weren’t quite so convinced.
“Loves a little Snapchat filter,” one person commented.
“If people don’t realise this is a filter they are delusional,” another person wrote, while someone simply said, “Love filters”.
One fan asked: “Is that for real? You’re not wearing something over your hair?”
A few eagle-eyed viewers decided it couldn’t be the TV personality because he “had no beard on Friday”.
Real or not, some of Stefanovic’s high-profile buddies were encouraging of the new look.
Olympian Michael Klim commented, “about time! Welcome to the club!”
While Larry Emdur quipped: “I’m looking in a mirror”.
Other comments compared Karl’s “new look” to Aussie chef Matt Moran, rival breakfast TV co-host David ‘Kochie’ Koch and some Hollywood celebrities.
“Omg! You look like Bruce Willis,” one person wrote.
“Its Karl Travolta,” another remarked.
“Hope you don’t find this offensive… first thought of John Travolta,” one person said.
One fan compared Stefanovic to former Savage Garden lead singer, saying, “You look like Daren Hayes!!!”
“George Calombaris’ long lost brother from another mother!” one person wrote.
And a handful of others thought the TV host resembled Aussie fashion designer Alex Perry sans glasses.
As one fan put it “cant wait to tune in on Monday” to find out if Stefanovic’s new look is a filter… or for real.
