Sam Armytage and Karl Stefanovic have brilliantly savaged each other on radio from London.

London might be a big city, but it would appear small enough for the Sunrise and Today Show crews to accidentally be holed up in the same hotel in the lead-up to the royal wedding.

Yes, as Australia’s two biggest morning shows broadcast live from London, The Daily Telegraph reports there are approximately 35 Nine staff and about 25 Seven staff all staying in the same hotel in St Pancras.

In a series of tongue-in-cheek barbs, Sunrise host Sam Armytage and Today Show host Karl Stefanovic traded blow after blow in a showdown on Fitzy and Wippa on Tuesday about the experience of staying in such close proximity to one another.

It began with the radio hosts desperate to probe Stefanovic on his relationship with the Sunrise stars.

“I haven’t run into Kochie, but I have run into Sam and Edwina [Bartholomew] on the flight over and the breakfast buffet. I am deliberately trying to stall their progress over here,” Stefanovic said, laughing.

“We are fierce [rivals], there’s no doubt about that. I can’t stand them. I can’t stand looking at them. I’ve read about how at each other’s throats they were … I think there’s cracks starting to appear,” he continued.

“I just want to have it on the record that there’s no dramas between us. But now, let’s do a sting on her,” he said, still joking.

The hosts then got Sam Armytage on the line.

“It’s Karl. You might know me from such shows as the Today Show in Australia,” Stefanovic introduced himself.

“Look, I’ve never watched it. I’ve heard it’s a bit second rate,” she said.

“Yeah, it is second rate — just not in Brisbane, Sydney or Melbourne,” he threw back.

Stefanovic then began to joke that he had been upgraded to a penthouse suite at the London hotel they are both staying in, offering to have “everyone around for a drink and to break bread”.

“Like, in the spa, do you think?” she asked.

I mean, probably not?
