Prince William and Prince Harry have a large extended family, including cousins from their mother Princess Diana's side. Diana had three siblings, all with children of their own, making them first cousins to the princes.
Among them is Louis Spencer, Viscount Althorp, 27, who is set to inherit the Spencer family estate, Althorp House in Northampton, where Diana grew up. Louis is the son of Charles Spencer, 9th Earl Spencer, and was born in 1994.
Louis grew up in Cape Town but later moved to the UK and studied at the University of Edinburgh. He has been praised for his resemblance to Prince Harry and was dubbed a 'Top Eligible Bachelor' by Tatler.
Despite the modernisation of succession laws in the UK, the Spencer family still follows primogeniture, meaning Louis will inherit the estate over his older sisters. His sister Lady Kitty Spencer has expressed support for this tradition.
Louis is known to be private and a talented actor, according to friends. He made headlines after meeting singer Nicki Minaj, who joked about marriage on Instagram.
