Thought you knew everything about the royal family? Well, have you heard of Prince Harry and Prince William's step-sister, Laura?
Yes, the royal brothers have a step-sister you have probably never heard of.
Laura Lopes (formerly Laura Parker Bowles) is the only daughter of Camilla Parker Bowles from her marriage to ex-husband Andrew.
Although Laura, 40, has made the decision to stay out of the spotlight, she reportedly gets along very well with her step-brothers.
Prince Harry and William even attended Laura's marriage to her accountant husband Harry Lopes in 2006, and it is most likely that she will attend the wedding of Harry and Meghan Markle in May this year.
Although you may not be too familiar with Laura, you might recognise her brother, 43-year-old Tom Parker Bowles.
The eldest child of Camilla appeared as a judge on Channel Nine's Family Food Fight in 2017.
