KATE Garraway was forced to pull out of attending filming after suffering a "crisis" - believed to involve her husband Derek.
The host, 55, revealed her secret hospital dash while presenting Good Morning Britain today.
She admitted she was expected to attend this year's Christmas Carol event hosted by Catherine, the Princess of Wales before having to cancel at the last minute.
Kate has been caring for Derek who fell ill at the start of the pandemic with coronavirus and was left fighting for his life.
Although she didn't reveal who was at the centre of the "crisis" a few weeks ago, Kate told GMB: "I was going to take my dad who has been looking forward to it for so long.
"But unfortunately we ended up back at the hospital with another crisis.

"It will be lovely to sit down and watch it with everybody else."
Kate was set to be one of 1,800 people at Westminster Abbey watching Kate Middleton's carol service.
The presenter said she will instead be "glued" to the TV when it airs on ITV after missing out to rush to the hospital.
The special carol concert, attended by members of the Royal Family, will air will air on Christmas Eve.

The service - filmed at Westminster Abbey - will also pay tribute to the late Queen.
ITV said in advance of the event: "The Princess of Wales will return to Westminster Abbey to host a special Christmas carol service on Thursday 15th December to recognise the selfless efforts of individuals, families and communities across the UK, and highlight the remarkable impact that coming together to support others can have for us all."
The Princess of Wales also appeared in a similar programme that aired days before Christmas on ITV last year.
She memorably played the piano alongside performances from Leona Lewis and Tom Walker.
