Prince William and Prince Harry have a half-sister named Laura Lopes. She is the daughter of Camilla Parker Bowles, the Duchess of Cornwall, and Andrew Parker Bowles, her first husband. Laura was born in 1978, two years before William and Harry were born.
Laura is not a member of the royal family and does not have a royal title. She has chosen to live a private life and has not been involved in any royal duties. She is a successful businesswoman and has her own fashion label. She is married to Harry Lopes, a former banker, and they have three children.
Laura's relationship with William and Harry is said to be close. They have been seen together on several occasions, including at royal weddings and funerals. In 2011, Laura spoke to The Times about her relationship with her half-brothers, saying that they are "like any other siblings."
"We all get on really well," she said. "We're all very close."
It is not clear why Laura has not been more involved in royal life. Some have speculated that she has chosen to keep a low profile in order to protect her privacy. Others have suggested that she has been excluded from royal life by the Queen or other members of the royal family.
Whatever the reason, Laura Lopes is a relatively unknown figure in the world of British royalty. However, she is a close member of the family and is said to be a loving and supportive sister to William and Harry.
