Prince Harry and Meghan reveal why they shared their baby news at the start of the royal tour

The Duke and Duchess of Sussex told family members about Meghan's pregnancy at Princess Eugenie's wedding, one day before departing on their royal tour.

The announcement was officially posted on Kensington Palace's official Twitter account shortly after the joyous couple touched down in Australia.

The simple reason for announcing the pregnancy at the start of their Australian tour was the location.

Prince Harry said at Admiralty House that they "couldn't think of a better place to announce the upcoming baby, be it a boy or a girl."

According to Kensington Palace, the baby is due in the spring of 2019, and the post on Instagram received half a million likes in only a few days.

Thanks to the timing of the announcement, they were showered with baby gifts throughout the 76 engagements in Australia, Fiji, Tonga, and New Zealand.

The pregnancy announcement follows just six months after they tied the knot at St. George's Chapel in Windsor back in May.

The couple had been dating since 2016 but only announced their relationship in November that year. They were spotted on a date in London soon after.

Meghan moved into Harry's cottage at Kensington Palace in December last year, after her contract with the TV series "Suits" came to an end.

Her first public appearance as Prince Harry's girlfriend followed five months later when she watched her prince play polo in Berkshire.

They were pictured showing public displays of affection in September when they attended the Invictus Games in Toronto.

Their child will be seventh in line to the throne, after Prince Charles, Prince William, Prince George, Princess Charlotte, Prince Louis, and Prince Harry.

That is too far down the line for the future Sussex baby to be styled as His or Her Royal Highness unless it is decreed by Queen Elizabeth II.
