Prince William and Prince Harry’s brotherly feud has been the subject of tabloid gossip for years – but they’re not the only siblings they’ve been at war with.

When their father Prince Charles married Camilla Parker-Bowles in 2005, the brothers gained not only a stepmother, but two stepsiblings – Laura and Tom Parker-Bowles.
Royal biographer Katie Nicholl revealed in her 2010 book Harry and William that in the early days of Charles and Camilla’s relationship and in the lead up to their wedding, William and his step-sister would argue bitterly.
“William and Laura used to have terrible fights over who was to blame for their broken homes,” Katie wrote.
“William would blame Camilla for all the hurt she had caused his mother, which would send Laura into a rage.
“Laura was not having any of it. She would take a hard line and fire back at William ‘your father has ruined my life.’”

However in time, the step siblings’ relationship softened and Laura and William made amends.
“When they stopped blaming one another’s parents and let go of their painful pasts, Laura and William got along well,” Katie wrote.
Both William and Harry, as well as Will’s then-girlfriend Kate Middleton, attended Laura’s wedding to chartered accountant Harry Lopes in 2006, and their daughter Eliza Lopes was one of the flower girls at the Duke and Duchess of Cambridge‘s wedding.
Laura and Harry also have twin boys, Gus and Louis.

Meanwhile, Aussie audiences may recognise Camilla’s son Tom Parker-Bowles from his days as a judge on Family Food Fight.
The food writer and father-of-two starred alongside Matt Moran and Anna Polyviou on Nine’s cooking show for two seasons and shares daughter Lola and son Freddy with wife Sara Buys.
But even though his mother is a duchess and his godfather is Prince Charles, Tom does not feel connected to the royal family.

Speaking to Good Morning Britain on the subject of the royal family, Tom explained, “My mother married into it. She’s part of it. We’re the common children. We’re just on the side.”
Despite this, both Tom and Laura’s positions could change when Charles becomes King.
According to a report by The Express, the Prince of Wales may bestow royal titles upon his stepchildren when he ascends to the throne.
