Meghan Markle, a pregnant woman, delights the royal audience with new photos

Only a few days ago, we learned that Prince Harry and Meghan, the Duchess of Sussex, were expecting their first child, and since then photos of these proud parents have given the royal observers a glimpse of their happiness during their tour in Australia.

But the last pictures of this tour gave these observers something else to see: a baby hump!

The former Meghan Markle came out Thursday in a tight-fitting navy dress from Australian stylist Dion Lee, and unlike the other dresses she's worn on their tour, this one highlighted a hint of her new bump.

But it was not his only look of the day. Later, she wore a Martin Grant trench coat and a Club Monaco black dress with a row of buttons on the side.

Of course, while the visual evidence of the baby on the way is thrilling for the fans, the duchess intended to focus on the task ahead Thursday.

After all, she and her prince were hard at work attending royal ceremonies, including two school visits, a stop at the beach to meet with a team of lifeguard rescuers, to a brief lesson from Australian football and, as always, a few stops to welcome huge groups of sympathizers along the way.

It was during one of these meetings that the Duke of Sussex involuntarily stirred up a new lesson.

At one point Prince Harry got to know a five-month-old baby, Harriet, and according to Keir Simmons of TODAY, he later said, "Harriet is a big name," which is exactly the kind of comment that feeds baby … name of speculations.

While Harriet would be a nice option if the newlyweds were expecting a little girl, Simmons reported that fans' current favorites for the next member of the royal family include Victoria, Albert, Arthur and Alice.

The truth is that the couple, who seemed particularly affectionate during Thursday's outings, has plenty of options to choose from. In fact, while taking a streetcar with students from Albert Park Elementary School, Meghan told them, "We have received a long list. We will sit and watch them.

And if they need more options, they can check our own list of potential nicknames.
