Princes William and Harry are arguably the most famous brothers in the world, but not everyone in their family live the same life they do in the spotlight.
The pair also have a stepbrother and a stepsister, who lead more private lives than William and Harry.
Tom Parker Bowles and Laura Lopes, are the children of step-mother Camilla, the Duchess of Cornwall who married Prince Charles in 2005.
Prior to their marriage, Camilla had previously been married to Andrew Parker Bowles and together they had two children.
While Tom is a well-known food writer and often appears on food and cookery TV shows, Laura leads a more private life, according to The Mirror.
She was educated at a Catholic girls boarding school in Dorset, and then studied History of Art and Marketing at Oxford Brookes University.
Before settling down, Laura worked as Tatler’s motoring correspondent then moved into the art world - managing The Space Gallery in London then co-founding London's Eleven Gallery in 2005, where she was also a director.
Laura married chartered accountant Harry Lopes in Wiltshire in 2006, an Eton College graduate who had spent some time as a Calvin Klein underwear model.
On their wedding day, Laura wore an Anna Valentine dress which was the same designer her mother wore when she married Prince Charles in 2005.
William and Harry were guests at her wedding and she attended both of their nuptials and her daughter Eliza was a bridesmaid at William's wedding in 2011 when she was just four.
Laura and Harry are parents to twins Gus and Louis, born in 2009, with Camilla close to all of her grandchildren.
Although Laura is not a royal, she could be in line to inherit two stately homes because her husband, the son of a baron, is set to take over Gnaton Hall in Devon, as well as the Skelpick estate in the Scottish Highlands.
Today Laura's mum Camilla and stepdad Charles joined William's wife Kate for a rare outing.
Kate was invited by her father-in-law on the visit to Trinity Buoy Wharf, a centre in East London run by the Prince's Foundation, where traditional textile skills are taught.
They then met students, who demonstrated their sewing machine skills and they even tried their hands at sewing a straight seam themselves.
