David and Victoria Beckham welcome their first daughter, Harper Seven

LOS ANGELES -- David and Victoria Beckham welcomed a baby girl, Harper, to their growing family Sunday, the soccer superstar announced on his Facebook page.

"I am so proud and excited to announce the birth of our daughter Harper Seven Beckham. She weighed a healthy 7lbs 10oz and arrived at 7.55 this morning, here in LA. Victoria is doing really well and her brothers are delighted to have a baby sister xx."

This is the fourth child for the US-based star British couple, who married in 1999, and the first daughter. She joins her older brothers, Brooklyn, 12, Romeo, eight, and Cruz, six, who "are excited to welcome their baby sister to the family," the spokesman said.

Victoria Beckham's fellow former Spice Girls members took to Twitter Sunday to congratulate the couple.

"@victoriabeckham congrats!!! Yipeee another spice baby is born, damn it wish it was me this AM cos I feel like I'm about to POP!" wrote "Scary Spice" Melanie Brown, who herself is heavily pregnant.

"Baby Spice" Emma Bunton tweeted, "Big kiss to @victoriabeckham can't wait to meet your gorgeous little girl!"

David Beckham's former England teammate Michael Owen was also among the well-wishers, posting, "I hear Victoria Beckham has just given birth to a baby girl. Great news," while talk show host Ellen DeGeneres wrote, "Congratulations to David and @VictoriaBeckham and their new baby girl! I can't wait to meet her."

News of the birth came just a day after David Beckham scored directly from a corner kick for the LA Galaxy and only three days after the former Manchester United and Real Madrid superstar posted a sneaky photograph of a heavily pregnant Victoria on his Facebook page.

Beckham, 36, said the black and white picture of his 37-year-old wife, which showed her reclining in the sun with her "bump" fully exposed, was taken without her knowing.

"Took this pic of Victoria while she wasn't looking. She looks amazing, so close now to the baby being born!" the caption read.
