As the world waits (kind of) patiently to learn whether there's any Prince Harry and Meghan Markle wedding news, at Brides HQ we couldn't help but speculate what might happen when the happy couple announce their engagement.

From hen dos to venues they might consider, here's a run down of the royal traditions and what we think will happen if our favourite redhead pops the question to the Suits actress.

1. Harry will ask his grandmother, the Queen, if he can put a ring on Meghan's finger. An act passed in 1772 states that the sovereign has the right to veto the marriage of a family member or can give formal content if happy with the plan.

According to the BBC, the Queen 'readily gave her consent' when Prince William declared his intentions to wed Kate Middleton back in 2010. If that isn't a sign that the Queen would welcome a Prince Harry and Meghan Markle wedding, we don't know what is. 

10 THINGS YOU DIDN'T KNOW ABOUT MEGHAN MARKLE

2. Westminster Abbey will likely be high on the couple's list of wedding venues. Formally titled Collegiate Church of St Peter at Westminster, the gothic building has been the stunning backdrop for numerous royal weddings since the Medieval times. It was also the church of choice for Prince William and Kate Middleton's wedding in 2011. 

However, if Harry and Meghan were planning a more intimate ceremony, the 100-seater Chapel Royal at St James' Palace could also be an option. It's here that Prince George was christened in 2013.

Alternatively, St Paul's Cathedral - where Prince Charles married Harry's mum Diana - or St George's Chapel at Windsor Castle could make the cut.

ROYAL WEDDINGS THROUGH THE AGES

3. Harry and Meghan will celebrate their last night of freedom with stag and hen parties

While we can only speculate about what the duo might get up to with their friends at this stage (perhaps Meghan will celebrate with BBFs including Serena Williams in her hometown or Toronto?), the details will almost certainly be shrouded in secrecy. It's well known Harry's a party boy, so perhaps he'll head to stag-do central, Las Vegas.

Let us remind you what went down at Wills and Kate's dos: Prince William is thought to have left London with a group of pals to spend the weekend at a country estate in Norfolk. Guests included best men Prince Harry and Guy Pelley.

Kate is also reported to have shunned heading out dancing all night in favour of a private party away from the paparazzi. Whether she played any hen party games, we'll never know.

4. Meghan's 'something borrowed' could well be a royal heirloom, if Kate's sparkling wedding accessory is anything to go by.

Kate wore a Cartier halo tiara decorated with 739 brilliant-cut diamonds and 149 baton diamonds with her gown as she walked down the aisle on 29th April 2011. The beautiful headpiece was originally gifted the the queen mother by King George VI before being passed down to the Queen on her 18th birthday.

MEGHAN MARKLE STYLE: WEDDING GUEST INSPIRATION

5. Prince Harry and Meghan's big day would attract A LOT of attention.

British officials estimated that 2 billion people tuned into around the world to watch the last Royal Wedding.

And Twitter went into overdrive with 300 tweets sent out per second as William and Kate exchanged vows. Facebook reported that 74 status updates posted per second referenced the royal wedding.

We've no doubt that an official Prince Harry and Meghan Markle wedding announcement would be just as popular. 

Though the will-they-won't-they question is still up in the air, we'll be sure to update you as soon as it's announced that Prince Harry and Megan Markle are engaged.
