David and Victoria Beckham welcomed their fourth child early Sunday morning, naming her Harper Seven Beckham. The baby is the first girl for the couple and a little sister to their boys Brooklyn, Romeo, and Cruz. The footballer confirmed the birth on his Facebook page. "I am so proud and excited to announce the birth of our daughter Harper Seven Beckham," he wrote. "She weighed a healthy 7lbs 10oz and arrived at 7.55 this morning, here in LA." Seven is thought to be a reference to Beckham's Manchester United jersey number as well as the hour and month of her birth; Harper is an old English name Victoria loves.
