A family spokesman confirmed on Sunday that 36-year-old Victoria is to give birth to the couple's first daughter in July.
The celebrity pair married in 1999 and have three sons, Brooklyn, 11, Romeo, eight, and Cruz, five.
They had already announced in January that fashion designer Victoria was pregnant.
35-year-old football star David, who captained England from 2000 to 2006, had hinted at the news late last week before the spokesman announced it.
