Speaking from his bed-and-breakfast hotel in the mountains of rural France, Mr Thevenet spoke of his happiness that his daughter had found love with James Middleton.

‘James is a very charming man,’ he said. ‘I am very happy that Alizee is together with James. I know she is very happy. We keep our fingers crossed for them.

‘I am not allowed to say how they met, to give away their secrets. You must talk to her or James, they will be back in London soon, but I’m very happy for them.

‘I have seen the pictures of Alizee and James in St Barts. They look very happy. Alizee is very happy living in London.’

Alizee joined James and his extended family including Pippa Middleton, 35, and her husband James Mathews, 43.

They were joined by 30-year-old reality star Spencer and his wife Vogue Williams. 

Earlier this week, Pippa was spotted carrying her 11-week-old son Arthur on the Caribbean island where her father-in-law owns a luxury hotel.

The two families are understood to have forged a close bond since Pippa and James tied the knot last year, with the Middletons invited to attend Spencer and Vogue’s wedding in Scotland. 

Kate’s younger sister has previously been seen on the island for winter holidays, including with her brother James in January 2016.

She married James Matthews in May 2017, and their first child – Arthur Michael William – was born in October. The pair live together in Chelsea. 

Their trip to the Americas this week comes after the Middleton family were spotted enjoying a casual lunch at a Berkshire pub on Boxing Day.

However they were not joined by Pippa’s sister Kate, who spent Christmas with the rest of the royal family – including Harry and Meghan – at the Queen’s beloved Sandringham estate in Norfolk.

The Matthews family owns the Eden Rock resort on St Barts, one of the region’s most exclusive hotels.

Stars including Elton John, Brad Pitt and Leonardo DiCaprio have stayed at the resort, where suites can cost up to £25,000 a night.

The hotel needed extensive repairs after it was wrecked by the devastating Hurricane Irma in September 2017.

James and Spencer’s parents, David and Jane Matthews, moved to St Barts in September 1995 after purchasing Eden Rock from local adventurer Rémy de Haenen.

St Barts has long attracted wealthy Europeans including Roman Abramovich, who bought a £49million mansion there and has moored his yacht on its shores.

Last week, pictures emerged of Paul McCartney enjoying a post-Christmas holiday on the Russian billionaire’s private boat.
