Beau’s birth comes 17 months after Robbie and Ayda’s third daughter Coco was born via the same surrogate.
They kept both pregnancies under wraps but Ayda shared the reason behind this when she announced Coco’s birth.
“It has been a very long and difficult path to get here, which is why we have kept it on the down low. Family comes in all forms, and this little lady, who is biologically ours, was carried by an incredible surrogate mother, to whom we will be eternally grateful,” she wrote on Instagram.
Robbie and Ayda are also parents to seven-year-old daughter Theodora and and five-year-old son Charlton.
