However, due to Meghan's increasingly big bump, many royal watchers are speculating that the due date may be a bit sooner than what the public have been told.
During the podcast, Mollard said: "I’ve done lots of counting on my fingers for how many weeks I think she is.
“When she was over here, she let slip to Missy Higgins at an event that she was 16 weeks, which would make her due in April.”
Mollard continued: “I have a theory with the royals that they tell you later dates than they think.
“If you say you’re due at the beginning of April, for instance, then you have everyone outside the Lindo wing of the hospital from the 25th of March.
“Interestingly Meghan did make a comment about the fact that babies can come early.
“She says she’s due at the end of April, but I think there’s a good chance we will see this baby born early April.
“I think she’s further along than she’s saying she is, I really do.”
