"Alex has already changed the baby and dressed him," Laura told HELLO! that morning. "He is gorgeous." Her little boy was delivered by emergency caesarean section.
The former Dancing on Ice star has been sharing her pregnancy experience in an exclusive blog on HELLO! Online.
Just two days ago, she revealed she that she was anxious for her baby to arrive.
"So it appears that all the people around me who were due to have their babies AFTER me have all had them ALREADY!," she wrote. "Clearly my baby bump is happy to stay put."
Laura and Alex announced their pregnancy news in June.
"We are absolutely over the moon," the Beat My Build star told HELLO!. "We feel so lucky that is happened so quickly for us, and I now have the beginnings of a bump."
Alex, who married Laura in September 2012, spoke of his excitement at becoming a dad.
"I didn't think I could possibly be more in love with Laura than I already was from day one," he said. "But now she's carrying our child we are even more in love.
"Seeing our little one on the screen really brought it home and made me think, 'Oh my word – I'm going to be a father'. Hearing the heartbeat for the first time is a sound I'll never forget."
The couple decided to keep the sex of their firstborn a surprise.
