Mike Hosking has been struck down with a mystery illness in London during a full on trip covering the All Blacks' World Cup win with his wife Kate Hawkesby.

Hawkesby might have some fans worried after sending out two tweets earlier today saying the Newstalk ZB host is "dying" in their Mayfair Hotel room.

She wrote: "When your husband's so sick he hasn't been able to get out of bed for days so Doctor has to come to Hotel. Bill = £200."

She later followed it up with this: "Gutted my shots of sick husband dying in a Mayfair Hotel bed didn't make the London snap story."

She also documented his illness on Instagram with several posts, one of the medicine she'd been out to buy Hosking.

The media power-couple have been in London for the Rugby World Cup, with Hawkesby writing in her latest Woman's Day column she had nabbed snaps with Richie McCaw and stand-out player Julian Savea.

"Like all the All Blacks that me and my hubby Mike saw, he [Savea] could not have been nicer or more helpful. Yes, he'd pose for a photo with me, no worries. Legend," she wrote.

Hawkesby said she also managed to blag her way into a luxury cocktail party in London for the unveiling of the new Webb Ellis Cup trophy case.

Meanwhile her presenter husband has been facing 4am starts to cover the games for TVNZ's Seven Sharp back home.
