Bookies say the size of the 37-year-old’s baby bump has led them to claim February as the favourite in their betting on the due date.
April comes in second with April a 5/2 chance.
Betway’s Alan Alger said: “Judging by the latest pictures of Meghan Markle, it looks as if her and Prince Harry’s first baby may not be too far away.
“In fact, we think it could be next month with February the favourite at 7/4, ahead of March at 9/4 and April at 5/2.
“There are a number of notable days during the next few months and while it’s unlikely the birth will fall on any of them, Valentine’s Day at 25/1 isn’t totally discounted.”
