Piers Morgan said he was 'heartbroken' as Kate Garraway shared an emotional update on her husband.
Kate said her husband is still "fighting" as she thanked the NHS staff who have been treating him for coronavirus.
The TV star's husband, Derek Draper, 52, a former lobbyist and political adviser, was taken to hospital at the end of March.
Alongside a video of her children banging drums during the Clap for Carers tribute to frontline workers, she said that the weekly gesture has been "a source of weekly comfort".
Commenting on this, Piers said: "This breaks my heart. Few happier, more positive people than @kategarraway. Or a more loyal, decent friend & colleague.
"So many families like hers going through so much unimaginable anguish in this crisis. Sending all my love to Kate & continuing to root for Derek."
With Thursday's clap potentially being the last after organiser Annemarie Plas called for it to stop, Kate said that she "felt the tears come tonight to think it's coming to an end before Derek's ordeal with us".
She added: "But whether we clap or not next Thursday my eternal thanks to all in the NHS goes on.
"They are keeping Derek alive and every one of them is fighting as hard as Derek is to give us the chance to be reunited."
Kate added: "It's not easy but when I think of how hard Derek is fighting and the bravery of all in the NHS it helps."
She added that she is "having to find new ways of staying strong everyday" for her children Darcey and Billy "as I know Derek would want me to".
She said that Billy thought they should "go out in style" by banging drums during the clap.
Kate has been sharing regular updates about Derek's condition following the Clap for Carers.
The couple married in 2005.
