Victoria Beckham is completely smitten with her brand new daughter.
"Baby Harper is the most beautiful baby girl I have ever seen," the former Spice Girl tweeted on Thursday. "I have fallen in love all over again."
"We feel so blessed and the boys love their baby sister so much."
The 37-year-old welcomed her first daughter in Los Angeles on Sunday morning via Caesarean section.
Her husband David announced the baby's arrival 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.
"Victoria is doing really well and her brothers are delighted to have a baby sister."
The couple's sons, Brooklyn, 12, Romeo, eight and six-year-old Cruz, are said to be enjoying quality time with the family's new addition.
It has been reported that they were behind the baby's name; Harper is the name of a character from Disney series Wizards of Waverly Place, the boys' favourite TV show.
