The 37-year-old fashion designer and her footballer husband David have spent four years in the states and want to mark their time there by welcoming their daughter on July 4.
According to The Sun, they originally booked a caesarean section for July 4 at London's private Portland hospital, but have since decided to change the location to Los Angeles, where they will rent a house for all their family to stay in.
A source told the newspaper, 'It's going to be a massive family affair in America. While the date hasn't changed, it was decided an LA clinic would be best for the immediate family.
'Vic and David love America, its culture and her people, who have welcomed them with open arms.
'The most important thing is the health of mother and baby and things can always change last minute.
'But if it's possible for the baby to be born on Independence Day, Vic and David will be thrilled.'
As far as names go, Atlanta is believed to be a strong contender because, 'David wanted a name that was relevant to their lives during the conception,' in reference to their constant jet-setting in between the US and England.
