Doria Ragland Has Arrived In London -- But Has Baby Sussex Beaten Her To It?

Has Meghan Markle already given birth to her and Prince Harry's first child?

Despite no official word from the Palace regarding Baby Sussex's arrival, rumours are swirling that the royal bub has in fact been born -- in secret.

We know, it's a crazy idea but it might just be true.

Now, as mum Doria has landed in London to see her daughter (and perhaps a grandchild?) things are just getting more and more complicated.

We break down the arguments for -- and against -- the theory that the Duke and Duchess of Sussex have already become first-time parents.

Yes, Baby Sussex is already here!
Meghan hasn't been seen for over a month

Yep, that's right -- mum-to-be Meghan hasn't been seen in public since March 19 when she and her husband attended a memorial for the victims of the Christchurch terrorist attack in London.

That was 35 days ago -- and counting. The Duchess was also noticeably absent from the Queen's birthday celebrations on April 21 where the whole royal brood turned out to wish Her Maj a happy 93rd.

Does this mean Meghan has had her hands otherwise full with a newborn Baby Sussex?

The couple has asked for privacy

Against royal tradition, Harry and Meghan have announced their intention to enjoy their first moments -- and potentially days -- as a brand new family of three in private, away from the public eye.

"The Duke and Duchess look forward to sharing the exciting news with everyone once they have had an opportunity to celebrate privately as a new family," said Buckingham Palace in a statement on April 11.

It's thought that the couple will do away with the customary post-birth photocall on the steps of the hospital -- which is unlikely to be the Lindo Wing where generations of royals have been welcomed.

The Duchess is instead suspected to be booked into Frimley Park Hospital in Surrey, close to their home in Windsor.

They've already sent 'thank yous' for their baby gifts

Another argument in support of the theory is the fact that the Duke and Duchess have already thanked the public for their generous baby gifts.

And by gifts, we mean donations to various causes which the charitable couple requested in lieu of presents.

The thinking is that Harry and Meghan would only send out their thank yous after their baby is born which has people wondering if the bub is already here ...

Meghan's makeup artist is already in town

Meghan's good friend and makeup artist Daniel Martin has been spotted in Windsor near the royal couple's new home at Frogmore Cottage according to UK site Express.

Martin has known the Duchess for years -- he did her wedding makeup -- and also attended her New York baby shower earlier this year.

Royal baby watchers are wondering if he's in town to help his friend prep for her first photos with Baby Sussex ...

Nope, we're still waiting for baby Sussex
Doria Ragland only just flew in

Meghan's mother, Doria Ragland has only just flown into London according to ET. This is a big point that could disprove the 'Baby Sussex is already born' theory simply because it's unlikely that the grandmother-to-be would've missed the birth of her only daughter's first child.

The Duchess has had her mum by her side for some of her life's major moments including her wedding to Harry in May 2018 and the launch of her charity cookbook.

Many royal watchers believe that Ragland's touching down on UK soil is the clue that Meghan's almost -- or perhaps already -- in labour.

The pair just celebrated Earth Day

Harry and Meghan had pulses racing when they shared a series of nine snaps on Instagram on Tuesday -- but it wasn't a  gallery of newborn Baby Sussex. We can only dream ...

The subject was, however, almost as close to the couple's heart. The photos -- many taken by the Duke himself -- were shared in honour of Earth Day and feature threatened and endangered animals and ecosystems.

The first snap -- of the Royal Highnesses walking hand in hand through giant redwood trees in Rotorua, New Zealand -- will have to suffice for now.

First-born babies are usually late

When Kensington Palace first announced Meghan's pregnancy on October 15, they revealed that the Duchess was due to give birth "in the spring of 2019."

The Palace hasn't revealed any further details but in January 2019, Markle reportedly told well-wishers that she was six months pregnant so she's likely to be due between late April and early May.

In Australia, 91 percent of babies were born 'at term' -- or between 37 and 41 weeks -- according to a 2015 government report. Plus, first-borns are more likely to arrive at 41 weeks -- or later.

So, we might be in for the long haul with Baby Sussex. If the Duchess' pregnancy looks like it'll continue past 41 weeks it's likely that she'll be induced.

The royals could have a reason to celebrate twice over if Baby Sussex's arrival creeps into May -- he or she could share a birthday with their cousin, Princess Charlotte whose birthday is May 2.
