The musician lost his wife and mother of his two children - Astala, three, and Phaedra, two - two years ago, and now he's spoken out about the aftermath of her tragic death at 25 years old.
Saying that he initially was not sure if he would go back to music, the 25 year old eventually decided to move to Iceland's capital Reykjavik four months later to get some 'space' and work on his solo album, The Mirror reports.
'Coming here [to Iceland] was the first bit of space I'd had. I was still a bit of a shell and I so needed it. You have to lose that context of yourself, in order to create what it is you're meant to create', the father-of-two said.
After losing his wife, who died as result of a drug overdose in April 2014 at their home in Wrotham, Thomas said he definitely closed off to the outside world.
'I definitely did clam up and close off. But I gradually realised that if you do that, you're kind of f***ing yourself. If you're repressing anything, and you have some sort of outlet, you should - or I felt that I should - definitely try to use it', Thomas said.
Thomas and Peaches with their son Phaedra before her death
Speaking of his upcoming album, Bloom Forever, Thomas said the most 'emotional' song is Morning Fall, which he wrote just a month before Peaches' death.
'I wrote it in my garden. It was the start of spring and days seemed to just come and go, and it all winds into this kind of dream-like state of not really knowing what you're doing or when', he told MOJO magazine.
'Like, some days in the countryside you just wake up and there's fog, and it doesn't leave, and at the end you go to bed. I guess the song is realising that something is coming to an end, but seeing the light in that.'
Peaches and Thomas got married in 2012, at her father Bob Geldof's Kent country mansion. It was the same chapel where Peaches' mother Paula Yates was buried in 2000, following her death by overdose. Bob Geldof's daughter died two years later, in the same circumstances as her mother.
Thomas was reportedly dating model Daisy Lowe
Two years after becoming a widower, Thomas has reportedly been dating model Daisy Lowe, who was also Peaches' best friend, but this hasn't been confirmed.
The two haven't spoken out about their relationship, with Daisy telling Now magazine she will 'never' talk about her personal life, but they've been spotted out several times, including once with Thomas' son Astala. 'I'm never going to talk about my personal life, never', Daisy said. 'I am so happy, thanks, yeah. I'm about good vibes all around.'
It's not confirmed if the pair are still together, after separation rumours surfaced earlier this month.
