Confessions of the girls who get married while still in their teens Average age of a British bride is now 30 years old Documentary follows three teens bucking the trend Not everyone is pleased - teens face parental opposition Two of the girls featured have already started families With the average woman now waiting until the age of 30 before walking down the aisle, brides in their teens and twenties are becoming an increasingly endangered species. But not everyone is prepared to wait, among them Lauren Scott, 18, from Lancashire, who recently married her boyfriend of 11 months, despite opposition from her mother. And Lauren isn't the only teenager keen to walk down the aisle at an age when most of her peers are focused on A-levels instead. Married at 18: Lauren, from Lancashire, and her now husband Duncan, pictured on their wedding day Young love: Aaron, 18, and Rebecca, from Newcastle, (left) and Ryan, 20, and Emmie (right), from Guildford Joining Ms Scott in new fly-on-the-wall documentary, Baby Face Brides, is Rebecca, a 17-year-old mother-of-one from Newcastle and the equally youthful Emmie Greenwood, 17, from Guildford, who also has a young baby. But although getting married as a teen might sound like a bad idea to many, all three insist that in their case, young love will last. Their confidence, however, doesn't appear to have rubbed off on their parents, with Lauren's mother Irene opposing the match and Rebecca's father choosing to stay away altogether. 'I wasn't too sure because I thought she was a bit young to be getting married,' admits Rebecca's mother Kathleen, who was herself a teen bride when she married at the age of 19. 'But then I thought if I didn't give my permission, it would spoil my relationship with her and she's going to be 18 in six months so she's just going to go and do it then anyway.' Committed: The pair met when Rebecca was 15 and four months pregnant with daughter Lily-Anne Family: Ryan and Emmie met when she was 15 and the pair now have a 18-month-old son named John-Roy For Lauren's mother Irene, accepting her daughter's plans was all the more difficult because Lauren, and her now-husband Duncan Murchison, 18, had been together for just four months when they got engaged. 'It came as a massive shock to me and her dad,' she reveals. 'It's all so rushed.' Poignantly, she adds: 'I just want her to be a baby still... Not grown-up. Despite parental opposition and very limited budgets, all three teens are seen throwing themselves into planning, while taking time to reminisce about the not always romantic proposals. Rebecca, who was 15 and four months pregnant when she met husband-to-be Aaron, said: 'It wasn't the most romantic [proposal] - he was kind of drunk after a big night out.' Fiance Aaron added: 'I tried to get down on one knee but I kind of fell over and was lying backwards. I'd been given a ring but it was one of my ma's. It was one my ma never used but it was a nice ring. The pair, who will live together with Rebecca's daughter Lily-Anne after the wedding, also spoke of their plans for their budget-conscious big day. Controversial: Lauren and Duncan, the pair with the biggest budget, faced the most parental opposition Budget: Rebecca, whose father chose not to attend, had just £2000 to spend on her big day 'We're going to get married but we don't have to have some big poshed up wedding,' explained pink-haired Rebecca, who is seen ordering a £56 dress from a Chinese website. 'I don't see the point in posh, flashy weddings - it's not what our family and friends would expect from us. We're not that type of person.' She adds: We'll be eating chicken goujons, sausage rolls, steak pie, chicken pie, cottage pie... It's pretty much Iceland's party food!' By contrast, Lauren, who had a budget of £10,000 courtesy of Duncan's parents, is filmed insisting on a classic country wedding, complete with a vintage car and a £1,500 dress. 'There was no need to wait for five years and grow older when you know it's what you want,' explains Duncan. The only thing I worry about is if [the wedding] is not good enough for Lauren. Lauren adds: 'If anybody is late on the day, including me, there'll be hell to pay!' Although the three brides eventually secure the perfect dress, venue and cake, one big question remains: do the teens really believe they can make their marriages work? 'It doesn't matter how old you are - if you love someone, you love someone,' says Aaron. His now wife adds: 'Aaron did the right thing by being strong for me when I was pregnant. A lot of lads of Aaron's age would have just walked away from you when you're having a baby and he didn't - he was there for me.' Lauren is equally confident. 'I'm very happy we're married. If it all goes balls-up in 10 years time, then it'll be our fault and no-one else's.' Baby Face Brides, Monday at 10pm on Channel 5
