Chat show host Jonathan Ross has told how he put off seeing his mother before she died from cancer because he "assumed she would be around for a lot longer".
Ross's mother Martha, who appeared in the BBC soap EastEnders as a market stall worker for many years, died in January.
Ross (58) said he had not realised how seriously ill she was, and regretted putting off visiting her in hospital until it was too late.
Speaking on Loose Women yesterday, he said: "My father is still alive, so this was the first of my parents that we lost.
"It is devastating. You know it's going to be a big loss, but you don't really know how it's going to feel. I don't know if you ever fully get over it."
When Ross announced his mother's death, stars including Shane Richie, Ant and Dec and Gaby Roslin paid tribute.
"What's awful is that I did see her shortly before her death, but then - well, she had cancer, but we were told that it was liveable with. We assumed she would be around for a lot longer," he said.
"Then she got ill and a phone call went around. We had a WhatsApp group.
"I feel bad because everyone said, 'We will all go and see her'. And I said, 'Let's not all go and see her today because then there's no one going tomorrow. Let's spread it out during the week. Who can only go today?'
"Two of them went, and she died that day - that last day that I would have seen her."
Ross paid tribute to his mother's love for her six children, saying: "One thing my mum did, and I'm sure this will strike a chord with some of you - whenever anyone would say, 'You must be so proud of Jonathan', she would go, 'I'm proud of all my children'."
Martha Ross also appeared in Grange Hill, The Sean Hughes Show, Space Virgins and Barrymore and hosted a current affairs show on Liberty Radio.
