Once upon a time they'd have been more likely to be found fishing or hunting rabbits than striking a pose for the camera - but now Traveller brothers Paddy, 16, and 15-year-old Liam are a firm fixture on the fashion scene.

The Doran brothers, who live in a council house with their parents in Kildare, outside of Dublin, caught the eye of the award-winning British photographer, Perry Ogden, when they were nine and 10 - the start of a flourishing creative partnership that has seen him make the boys the subject of his new book.

And since being discovered the redheads - both keen boxers - have been booked by some of the world's biggest fashion brands - from Burberry and Fred Perry to H&M.

They've caused such a sensation in the fashion world, the teenagers have also been hand-picked by David Beckham to feature in the campaign for his partnership with the British fashion brand Kent & Curwen.

Perry's new book, 'Paddy & Liam', focuses on the boys' lives as part of the Traveller community, and captures them in a series of fascinating images against the backdrop of the wild Irish landscape.

The photographer, whose work has appeared in Italian Vogue, and who has shot advertising campaigns for Ralph Lauren, Chloe and Calvin Klein, described the brothers as 'full of energy'.

The brothers, who live in Celbridge, Co Kildare, joined Perry during an appearance on Ireland's The Late Late Show to talk about their flourishing modelling careers.

'We've been photographed since [we were younger] and now it's just normal for us, for Perry to call us and say "do you want to do a shoot",' Liam explained.

And Paddy said of his plans for the future: 'I would like to do [modelling] full-time.

'People taking photos and getting good pay it's not bad like!' he joked as the audience laughed.

Perry, who moved to Ireland in 1985, said he has always had an interest in Traveller culture: 'It's the sense of being an outsider, and in some sense I was a bit of an outsider as well.'

Thanks in part to Perry's influence the boys have become a fashion sensation, starring in a campaign for Fred Perry

The photographer, who personally recommended the boys to Beckham for his fashion campaign, first met them through their parents, Tommy and Mary.

He explained on the Irish chat show that the family had been living on the side of a crossroad two decades ago when a terrible accident divided their extended family and they wanted to leave.

Perry's then partner Marina Guinness, with whom he shares a daughter, was living down the road and had become friendly with the couple.

With a huge amount of land at the back of her property, she offered Tommy and Mary a place to moor their caravan and they raised their children in the back garden, meaning Guinness and Perry watched the boys grow up.

'When they were about nine or ten I was asked to do a story about anything I wanted in Ireland and I thought it would be great to photograph Liam and Paddy.

'I thought it was an interesting story and their parents were looking to get housed. They were having problems getting housed, and Paddy and Liam were the first generation of their family to have a primary education, and they had a great story.

'They were great looking guys, they had striking faces and were full of energy and I thought there was something great here.'

Perry said the idea behind his book was to document the youngster's lives through their formative years

It's been a year since the Traveller community were given ethnic status in Ireland.

Perry said the idea behind his book was to document the youngster's lives.

'I thought these images would make a very interesting book documenting that period of time from age ten to 16, which is such a transformative period in your life, a time when you are making discoveries and developing passions.

'I also wanted to reflect on the Ireland they were born into and the Ireland in which they are becoming adults.'

In the new book the boys are photographed in often wild, rural surroundings. They are often pictured with horses or dogs. Accompanying each image is commentary from the boys.

Next to one photograph of the brothers and their dogs, the caption reads: 'We been hunting now for six or seven years. We go anywhere where there’s rabbits. Every night we go out we come back with at least three or four.

'Sometimes when the dog gets very tired I put a collar on Liam.'

Perry Ogden’s Paddy & Liam was released on 16 March and is published by IDEA
