What's not in doubt is that the couple are thrilled. They were recently spotted in the street near their London home, with the little one strapped to mummy's front.
At the weekend, Guy and Jacqui also had an adults-only outing to Wimbledon.
Along with a host of celebrities including the Duchess of Cambridge, née Kate Midddleton, Prince William, Victoria and David Beckham and Samuel L Jackson, the parents watched the gripping five-set final between Roger Federer and Novak Djokovic .
The newborn will have lots of siblings to play with - Rafael, who will be three in September, and Rivka, 18 months, plus Rocco,13, and David, eight.
The two older boys are from the film director's marriage to Madonna. "Fatherhood is great," he enthused just after the Queen of Pop gave birth to Rocco. "It's unlike anything else I've experienced and it's always going to come first for me now."
Guy and Madonna went on to adopt David from Malawi in 2006, two years before their marriage crumbled.
He met Jacqui, a model, through friends in 2009 and they began dating the following year. Nine months into their courtship she discovered she was pregnant.
After having Rafael in 2011, she admitted: "I'd love more children. Guy and I have always wanted a big family. It's something we planned all along."
Guy couldn't be happier with the plan. In October last year the couple were seen on a stroll in Rome, where the film maker was shooting his movie The Man from U.N.C.L.E.
He looked the picture of contentment, carrying one of his children on his shoulders and stopping every now and then to give Jacqui an affectionate kiss.
