David and Victoria Beckham have released photos of their newborn daughter, Harper Seven, via their Facebook and Twitter accounts. In this photo, tweeted by Victoria, 37, with the caption "Daddy's little girl!", David, 36, is pictured touching noses with his only daughter, born on July 10.

The Beckhams have three other children — all boys. Brooklyn, 12, Romeo, 8, and Cruz, 6, live with the couple in Los Angeles, where David plays for the Los Angeles Galaxy. The English footballer and former Spice Girl wed in 1999 in the UK and moved to Beverly Hills in 2007.

Explaining the origin his daughter's name, David said there were two main reasons why he and Victoria chose the name Harper. "One reason is Harper's an old English name which we loved," he told the U.K.'s Daily Mail, "and one of the other reasons was Victoria's favorite book is To Kill a Mockingbird and the author was Harper Lee. It's a very strong, passionate book."
