Getting ready: Victoria and David Beckham get ready for the arrival of their daughter as they prepare on a birthing ball
She's already mother to three sons, so Victoria Beckham knows now what's involved in giving birth.
But it seems as she prepares for the arrival of her first daughter, Victoria is getting some help from husband David with her breathing.
In astonishing new photos, the pair are seen sitting on a birthing ball, with David's hands clasped around Victoria's pregnant tummy.
'What about Gucci?' In another shot set up by celebrity photographer Alison Jackson and featuring lookalike sees 'Victoria and David' discuss names
In another shot, Victoria and David are seen trying to choose from an unusual list of baby names.
With ideas including Benditlike, Gucci and Santa Monica, Victoria clutches a book of 1000 Girl's Names, while David reads America's Favourite Baby Names.
However, as you may have guessed, the pictures aren't actually of the famous couple but instead of lookalikes, set up for a series of pictures taken by celebrity photographer Alison Jackson.
Out and about: Victoria and David were spotted driving around Los Angeles on Wednesday
Jackson shot to fame when she put together a picture which apparently showed Princess Diana, Dodi Al-Fayed and a mixed-race baby.
But Jackson, who also produces pictures of royal family lookalikes, admitted recently her work takes a lot of time.
Describing how she sets up for a shot, Jackson said: 'I draw up lists of what is needed, contact the various experts such as wig and clothes-makers, make-up artists and lookalike models - and then work closely with them to achieve the exact look I’m seeking.
New addition: David and Victoria are already parents to sons Brooklyn, Romeo and Cruz
'Ultimately, though, it’s up to me to capture the right moment where they all look as I envisaged.
'All this is very expensive; consequently, I don’t take many photographs, maybe one or two a month.'
Victoria and David's little girl, who is due on July 4, will be Victoria and David's fourth child and first daughter and sister for eight-year-old Romeo, Brooklyn, 12, and Cruz, six.
