Bob Geldof has spoken movingly of his daughter Peaches - three months after she tragically died with heroin in her system.

Speaking to Lorraine Kelly on ITV after Peaches' death nearly three months ago, the father-of-four told of his intolerable pain.

The 25-year-old mother-of-two was found dead by her husband Thomas Cohen in a bedroom at their Fairseat Lane, Wrotham home. An inquest opening heard heroin had played a part in her death.

She leaves behind two sons, Astala and Phaedra.

But Bob Geldof said he is finding some peace in his music, saying: "It's intolerable - it's very hard as everybody must realise, especially if it happened to them too, and what else do you do, you get on with it."

Speaking about the lyrics to the Boomtown Rats hit Diamond Smiles, the musician said he sometimes now recognises his late ex-wife Paula Yates and daughter Peaches in the song words, saying: "There's a song we had that was a big hit, [that] the Rats had called ‘Diamond Smiles’ - it was the one after ‘I Don’t Like Mondays’.

"It was a very big hit and I was writing about a girl I read about in one of the papers, she was a socialite, and she went to a posh party, it was only a small item but it struck with me, and she went to a party and she went upstairs and hanged herself during the party.

"It's intolerable - it's very hard as everybody must realise, especially if it happened to them too, and what else do you do, you get on with it" - Bob Geldof

"And it was a tiny little piece and I think that somebody said 'she was the brightest of diamonds' and I called the song Diamond Smiles.

"If I really think about those words - and usually I'm in the zone of that song - if I really think about it, it's too bizarre, it's too telling whether it's about Paula or now whether it's about Peaches, and stuff like that."

Sir Bob said there were still reminders of his daughter in his everyday life.

He said: "You could be talking to somebody, you could be walking down the road, and - I've got to be very careful because this is still very raw - but I’m walking down the road and suddenly out of the blue there's an awareness of, her and you know, I buckle and I’ve got to be very careful because walking down the Kings Road there are paps everywhere so I have to duck off into a lane or something, and blub for a while and then get on with it and that's it, so I'd imagine that will be there for a long time, I mean what else."

Talking about feeling overwhelmed by the letters of support from the public, Bob also spoke of his pride of his daughter and the impression she left behind.

He told Lorraine: "The nice thing about that was that this young girl had made such an impact, especially on her generation.

"When the Rats got back together last year we went out on tour I was walking around Leeds… and people would come up to me and say 'You're Peaches Geldof's Dad aren't you?' and I'd say 'yes', but I liked it, I liked being Peaches Geldof's Dad."

He also spoke of Peaches' sons, and his feelings towards his own mother, who died when he was young.

The grandfather said maybe the 'Geldof' life wouldn't be the best route for the young boys, and gave praise to their other grandparents.

Bob said: "My mum died when I was six or seven, I have no memory of her but as you say, the world has moved on.

"I am shown photos, I really have no interest in that much because I have no memory of her.

"So I don’t really remember her and I'm not sure that - they are so small the little chaps - that I'm not sure that they'll have this craving to remember their mum, and I think that is healthy.

"They are young enough, you know this terrible expression, to be able to build on emotional relationships away from the primary relationship with the mother."

Looking forward to marrying long term partner Jeanne Marine, the 62-year-old, who lives in Faversham, admitted the engagement provided some light into the family.

He said: "I love her to bits."

He then admitted that even if he will not sing at his wedding, he’s hoping his wife-to-be will.

He said: "I hope she does [sing at the wedding] because she has got an amazing voice.

"She was at Glastonbury with Jerry Hall, who's her great friend - our great friend - it'll be great but if it's not October it’ll be next year, spring, there’s no urgency."

Sir Bob went on to speak of his band of nearly 40 years, The Boomtown Rats.

He said: "I love it, particularly I love playing because it... well I wouldn’t do it if it wasn’t a great band so you’ll have to take that as a given.

"I think not only did I rediscover the Rats were a great band - you never get it as a kid, you just grow up with these guys and just form a band and that’s your thing - but with a gap of time where I played solo stuff and we got back, I hadn’t realised quite how, you know unapologetically I say, how great a band it is."
