Kelsey Parker has spoken about how she held Tom's hand as he died as she opened up for the first time since his death.
The 32-year-old recalled it being "beautiful until the end" and said that he "wasn't in any pain".
The Wanted singer Tom tragically died aged just 33 in March, 18 months after he was diagnosed with brain cancer.
Kelsey, who is mother to two children with Tom, opened up about his final hours in the hospice and how they shared a final kiss.
Speaking to The Sun on Sunday, she said: "It was still beautiful until the very end. It was just us and there was so much love in that room.”
In tears, Kelsey said that she got into bed with him and that they were together for two hours in there as she just wanted that time with him.
"I didn’t want anyone coming in," she said. "We needed that time together to talk."
Kelsey described it as "romantic" even though they were in a hospice together and said that Tom had always been "so romantic, loving and caring".
Recalling the last conversation she had with Tom, Kelsey said: "I said, ‘You know Tom, I will be OK, the kids will be OK. I will make sure that everything you want them to know, the things that you’ve taught me over the years, I promise to teach them it all’.
“He said, ‘I know you’re going to be OK’. He then took off his wedding ring and put it on my finger."
Kelsey recently shared a touching photo of her daughter Aurelia holding a feather on Instagram as she said "daddy has come to visit".
She revealed that Tom had promised to send her signs every day before he died.
The mum recalled sitting on a bench crying when a feather fell from the sky.
Kelsey said: “I said to Tom before he passed away, ‘Will you give me signs every day’, and he said, ‘Yes’. I knew straight away it was him.
"I kept that feather, I still have it in a little glass pot on my dressing table.”
Kelsey said that telling their children that Tom had died was "really tough" and that the words got "stuck in her throat".
Ever since Tom was diagnosed with cancer, the couple have resolved to be honest with two-year-old Aurelia and 18-month-old Bodhi.
Speaking about the moment she told Aurelia, Kelsey said: "I couldn’t talk, it was like I had something stuck in my throat, I couldn’t say it but I knew I had to say those words to her because she had to know."
It comes after Kelsey shared a heartfelt poem on her Instagram stories last week following her husband's funeral.
She said: "Grief may feel like the dying of the soul while the body still lives, but you are alive my friend.
“And they are not, nor do they want you to be with them just yet. They very much want you to live.”
The poem continued: “Do not fear the grief you feel, it’s just love thrashing around, looking for somewhere to go. So give it somewhere to go.”
At the end of the post, it said the poem was called ‘I Wish I Knew’ by Donna Ashworth.
Tom's funeral was held on April 20 at St Francis of Assisi Church in Petts Wood, south east London.
Fans were invited to line the streets and welcomed outside the church as the service was played out on screens.
Tom’s The Wanted bandmates Max George, Siva Kaneswaran, Nathan Sykes and Jay McGuiness were the pallbearers.
His poignant funeral song was reportedly Live Forever by Oasis, which was said to be playing as he died surrounded by friends and family.
In a pre-recorded eulogy at the service which left the congregation in tears, Kelsey called Tom her “soulmate” and said he had “taught their children how to be brave”.
She added the boy band star would still be alive today “if love alone could have saved him”.
Kelsey said that she and Tom had never discussed his funeral arrangements but believes he would have loved it.
Explaining that she doesn't believe that Tom realised how many hearts he touched, she added: "I try to tell myself how lucky I am. How lucky I was to find Tom, the love of my life, my soulmate and best friend."
