They lead lives governed by pecking order, tradition and protocol (sounds fun, right?) - so it's safe to assume the royals are pretty deliberate when making a public statement.
Take the nuptials of Lady Gabriella Windsor and Thomas Kingston. While Gabriella is 52nd in line to the throne, it was still a royal wedding attended by senior members of the family - including the Queen herself.
You don't get much more senior than the Queen .
Also in attendance was Princess Beatrice who arrived with her mum, Fergie, and her boyfriend, Edoardo Mapelli Mozzi.

This is significant, because it marks the couple's first public appearance together at a royal event.
While the pair have made appearances at high profile events such as the Bahrain Grand Prix, bringing your partner along to a family wedding when you're royal is a big deal.
Royal Family members only tend to bring dates along to functions when things are serious.
The Duke and Duchess of Cambridge had been together for five years when the then Kate Middleton scored an invite to Peter Phillips' wedding.

It's believed that this was the occasion where she was in fact introduced to the Queen.
Also consider this - with the exception of Meghan Markle , no non-married partners have ever been allowed to spend a Christmas at Sandringham with the royals.
So by Beatrice bringing Edoardo along potentially says a lot - could there be another royal wedding in the pipeline?
According to 9Honey , Beatrice and Edoardo were friends for years before things turned romantic.

The 34-year-old real estate firm CEO is a family friend of the Royals, with Prince Andrew, Fergie and Beatrice all attending his late stepdad's funeral in 2011.
