However, Pippa opted to take in the tennis with ex-boyfriend George Percy, rather than current partner Alex Loudon, who joined her as she wore a striking red dress on Wednesday.
The princess' sibling wowed crowds on the famous court by wearing a trendy knitted dress which showed off her bra and svelte figure along with huge sunglasses.
The estate includes Alnwick Castle – better known as the setting for Hogwarts in the Harry Potter films – and his family are regarded as royalty in the border territory.
Pippa also left Loudon at home last month when she and Percy enjoyed a short break in Madrid, while they were spotted at the Queen's tennis tournament a fortnight ago.
As well as watching on as British number one Murray crashed out of the tournament to Rafael Nadal, Pippa took in the earlier semi-final between Novak Djokovic and Jo-Wilfriend Tsonga.
