If you have children, have ever babysat or have nieces or nephews, then you will be familiar with Peppa Pig.

The animated pig character, along with her brother George, are hugely popular in most houses. Not only can you get them on TV, but also DVDs and on YouTube, so there is no end to the supply of episodes. Not to mention the books and merchandise to go along with it. But, even though we've patiently sat through hours of Peppa Pig, we've never given much thought about who voices the central character. Turns out it's a fifteen-year-old girl called Harley Bird. When it comes to voices of children's characters they're usually much older. Nancy Cartright, who is 59-years-old, voices Bart Simpson and Yeardley Smith, who is 52-years-old, voices Lisa Simpson. So, we just thought that the same pattern would follow for other shows. But Harley has been the voice of Peppa for the last ten years. She started at the age of five and can still create the same voice of little Peppa as a teenager. She was on This Morning earlier today when she did the voice for Phillip and guest host Sarah Greene and they loved it.
