Gary Barlow was determined to step up for his wife Dawn after their daughter was stillborn.
The 47-year-old pop star and Dawn suffered the heartbreak of losing their daughter Poppy in August 2012, and Gary says he immediately turned his attention towards supporting his wife through their anguish.
Gary - who has been married to Dawn since 2000 - shared: "The way I was thinking around Poppy's death was, I've got to look after Dawn. It wasn't about me, it was about her and me stepping up as a husband.
"When you say you are going to be together and you take those vows, you look after your partner, that's just what you do. It's how you react in that situation. She's just amazing."
Despite the emotional turmoil, Gary performed at the London 2012 Olympic Games Closing Ceremony.
But the British star has admitted he's never watched his performance back and that it was a "tough" moment for him.
Gary - who has Daniel, 18, Emily, 16, and Daisy, nine, with Dawn - told ITV's 'Lorraine': "It felt like a job, I've just got to get on and got to get off again.
"It was really going through the motions for me, I was in my own world. I have never watched it back. I don't know what was going on in my head. It was tough."
Gary previously revealed that he hopes talking about his own heartbreak will encourage other people to follow suit.
The Take That star explained: "After Poppy died, people wrote to me about suffering the same awful experience. Many had kept so much of it locked away in secret.
"I've wondered about the value and purpose in sharing something so private, but I'd have been denying Poppy her legacy not to. Maybe sharing our story will help others talk about theirs."
