Could Archie have a new brother or sister on the way?
The Duke and Duchess of Sussex welcomed their first child together in May this year, with Prince Harry revealing since that the couple are hoping to have more children.
"Two, maximum!" Harry told primatologist Dr Jane Goodall in July.
"I’ve always thought: This place is borrowed. And surely, as intelligent as we all are or as evolved as we all are supposed to be, we should be able to leave something better behind for the next generation."
Since the comments, Meghan has unsurprisingly been on baby number two watch, with people convinced that another baby announcement from the Sussex family is on its way.
‘The odds of Meghan and Harry sharing some good news soon have taken another plunge,' they wrote in a statement.
'The latest betting definitely suggests there could be an announcement around the corner and when it comes bookies should brace themselves for another royal betting frenzy.'
Another that eagle-eyed member of the media believe that a new baby could be on the way is down to the way that Markle has been dressing.
We know the Duchess likes to recycle her clothes. She's often seen repeating outfits in an attempt to share the importance of slow fashion.
However, more recently, attention has been drawn to the fact that Meghan has been specifically recycling some of her maternity clothes recently.
During the Sussexes tour of Africa, Meghan re-wore a shirt dress she first donned while pregnant on the royal tour last Autumn.
Also in South Africa, Meghan chose a khaki striped maxi dress by Aussie designer Martin Grant for one engagement - also worn for the first time during her official visit to Australia last year.
While, of course, the new mother may just be getting good use out of her recently purchased maternity wear, insiders believe that the arrival of another royal baby could be announced any day now.
Finally, royal fans think Prince Harry and Meghan Markle could be expecting baby number two after the Duchess was pictured with her hand placed over her belly last night.
The royals all attended the Festival of Remembrance at the Royal Albert Hall, and Meghan and Harry were pictured on the balcony.

This evening The Duke and Duchess of Sussex accompanied Her Majesty The Queen and members of @TheRoyalFamily to the annual @RoyalBritishLegion Festival of Remembrance. This special event, which has taken place every year since 1923 at the @RoyalAlbertHall, commemorates all those who have lost their lives in conflicts. • This year’s Festival marked the 75th anniversary of a number of crucial battles of 1944, with a particular emphasis on the collaboration and friendship of the British, Commonwealth and Allied armies who fought them. A unique tribute was given to acknowledge those involved both past and present, culminating in a special parade of some of the last surviving veterans who fought and served in 1944. • Their Royal Highnesses, who last year attended their first Festival of Remembrance together, were honoured to once again pay tribute to all casualties of war and remember those that have made the ultimate sacrifice for their country. #FestivalOfRemembrance #WeWillRememberThem Photo © PA / Royal British Legion
Of course, there's absolutely no concrete evidence that Meghan is pregnant, and we know she always looks glowing no matter what, but Prince Harry did seem to drop a hint earlier this week that a new baby Sussex could be imminent.
During a visit to the military families with Meghan on Wednesday last (November 6), Harry appeared to have children on the brain after asking parents what it would be like to add a second baby into the mix.
“Harry was really quite interested in how things were with second children as well, because we both have older children,” Susie Stringfellow told Forces Network.
She added: “We were trying to encourage him to have a second baby."
