David and Victoria Beckham have posted pictures of themselves with baby Harper Seven on social networking sites. Victoria shared the black and white snap of her husband cradling the child with her 1.5m followers on Twitter with the caption: "Daddy's little girl!" And David posted a similar photo, this time of his wife and new daughter, on Facebook saying: "I took this picture of my two girls sleeping." Harper, who is their fourth child, was born in Los Angeles on 10 July. On Friday, the footballer posted on Facebook that the baby had been named after To Kill A Mockingbird author Harper Lee. He said: "Victoria's favourite book is To Kill A Mockingbird, it's a very strong, passionate book and the author was Harper Lee, and that is where Harper came from.
