Harry and William's secret step-sister will be at the royal wedding

Sarah Carty

If you thought you were the biggest royal fan out there, who can name everyone in line to the throne in minutes, then did you know that Prince Harry and Prince William have a forgotten step-sister?

The much-loved royal brothers are part of a massive family, with the Queen having eight grandchildren alone and an expanding brood of great-grandchildren.

However, while many of us could probably name the majority of the royals we see on the Buckingham Palace balcony at official events, there are other members of the family that shy away from the spotlight.

That’s exactly what Prince Harry and Prince William’s step-sister Laura Lopes likes to do.

Laura is the daughter of Camilla, Duchess of Cornwall and her first husband, Andrew Parker Bowles.

The 40-year-old tied the knot to Harry Lopes in 2006, with both Prince Harry and Prince William in attendance.

Also at the lavish ceremony, which was held in Wiltshire, was Prince William’s then girlfriend Kate Middleton.

And when Prince William and Kate Middleton decided to wed in 2011, they had Laura’s adorable daughter Eliza as their flower girl.

It’s believed that the royal family get on famously with Laura and there’s no doubt she’ll have a prime spot up the front of the Windsor Chapel.

Laura’s brother, Camilla’s son, Tom Parker Bowles, has also been spotted with the royal brothers over the years.

He has a 10-year-old daughter, called Lola, who also may be part of the bridal party.
