Gary Barlow has said he hopes that writing about he and his wife Dawn's stillborn daughter Poppy will help other people who have experienced the same tragedy.
The Take That star and his wife lost their daughter when she was delivered stillborn at full term in 2012.
Barlow explained that the chapter in his new autobiography, A Better Me, about Poppy was re-written three times and said that he and his wife changed their minds several times about including it.
Speaking emotionally at the Cheltenham literature festival, he said: "The first time was very inaccurate in the way I remembered it, so I sat and wrote the last version with Dawn.
"The thing that made us decide was how it will actually help other people. There is one thing about this, is that is has not really been talked about much.
"People say things like, 'You've got three other kids' and people don't really understand your pain, it makes it more painful. For us it was the chance to help all the other people who are not understood either. It just felt like the right thing to do and the right thing to be in this book."
"All the comments I have ever had, everyone has been unbelievably supportive and I really thank everybody for that, he added.
Barlow also opened up about the moment his wife phoned him to tell him Poppy had died.

"It just felt like one of those unbelievably strange days. Dawn had not been feeling well, she had shot off back to London and we were two days off the due date," he said. "I got a phone call and Dawn said, 'I can't think of any other way of saying this but the baby has died'.
"The doctor had given her a scan and said he had the most terrible news. I just went into this flight-or-fight mode. We went in the following night and it was a very strange day and the doctor had told me that you get to hold the baby.
"I was just dreading this thing happening and when she did give birth, it was amazing. We had the most incredible hour with our daughter. It was like a light coming into the room. It was gorgeous, both holding her, taking photographs and footprints, it was the most gorgeous hour.
"We had our moment and we were kind of happy with it and then we went home to a very empty house. Then we started organising the funeral because these things need organising.
"It was a very strange time but as the man in the middle of all of this, it was very heart-breaking watching the person that you love walking around the room with their dead baby. I just wanted to take care of her, that was all that was on my mind."
The couple have been married since 2000 and have three other children, Daniel, Emily and Daisy.
He said that he does not think his family will over get over the loss of Poppy.
"At that point I wasn't even starting to grieve, really, because I wanted to take care of her because we had three other kids," Barlow said.
"We all just looked after Dawn. We tried to be there for her. It is something I don't think we will ever recover from, especially her."
