Harry shares a close bond with his cousin Eugenie and she was reportedly one of the first members of the royal family to know about his relationship with former actress Meghan.
According to royal biography Finding Freedom: "Harry had always confided in his cousin when it came to the women in his life. Not only did he trust her implicitly, but friends say that she gives great advice and has always been 'beyond wise' for her years. It's not surprising, then, that Eugenie was one of the first in the family to know about his relationship with Meghan."

The couples also reportedly enjoyed a holiday together with the biography claiming that Eugenie and Jack's visit to George and Amal Clooney's villa on Lake Como overlapped with Harry and Meghan's trip in summer 2018. Jack works as a brand ambassador for Casamigos, a tequila company co-founded by George in 2013.
Eugenie has always been publicly supportive of her cousin, particularly on her own Instagram account. When Harry and Meghan's son Archie arrived in May 2019, Eugenie posted a photo of the couple in St George's Hall in Windsor on the day they introduced the royal tot to the world, writing: "I'm just so happy for you!! @sussexroyal."
