Her Royal Hotness! Pippa Middleton, 40, looks sensational in a £232 Vix bikini as she enjoys the sun in St Barts with her husband and young children

It’s been 13 years since she stole the show in that figure-hugging dress at her sister Catherine’s wedding, setting social media on fire and earning the title Her Royal Hotness.

But despite having three children since then, the Princess of Wales’ younger brother Pippa Middleton looks as slim as she did on that historic day as she strolls along a beach on the Caribbean island of St. Barts.

The 40-year-old showed off her toned physique in a £232 bikini from luxury swimwear brand Vix and looked sensational.

Pippa and her husband, James Matthews, are staying at his parents’ exclusive hotel, Eden Rock, on the sun-drenched island.

But while his wife looked suitably glamorous at a resort that attracts the likes of Brad Pitt and Leonardo DiCaprio, James preferred to be put off.

Even his chic £320 swim trunks from the Eden Rock store can’t distract from the impression that the 48-year-old banker forgot to apply sunscreen when he pulled out an airfoil board – similar to a surfboard, but with ‘wings’ underneath to help lift him out of the water.

Before her wedding in 2017, adrenaline junkie Pippa took part in the 3,000-mile Cycling Race across America, the 4-mile Bosphorus Cross-Continental Skiing Race and the London to Brighton Bike Ride.

She also joined James and brother-in-law Spencer Matthews in a 75km swim in Sweden to raise money for the Michael Matthews Foundation, a charity set up in memory of her husband’s brother, Michael, who died during the descent from Mount Everest. in 1999.

But after becoming a mother, she was forced to cut back on her regimen. “Running and fitness are still part of my weekly routine, but not at the level it was before,” she has admitted.

While her sister frolicks in the sun, the Princess of Wales recovers from abdominal surgery 4,000 miles away at the Sandringham estate.

Yesterday it was revealed that the Prince of Wales will attend the Bafta film awards in London alone on Sunday while Kate recovers from the procedure in Norfolk.

William, chairman of the British Academy of Film and Television Arts (Bafta), is attending his first high-profile royal engagement since his wife’s surgery in January.

It was initially thought he would miss Sunday’s event at the Royal Festival Hall at the Southbank Centre.

Last year he attended the ceremony with the Princess of Wales, where they met award winners Cate Blanchett, Austin Butler and Emma Mackey.

Kate underwent surgery at the London Clinic on January 16 and has since returned to Adelaide Cottage in Windsor to be with their three children.

Since the royal health announcements, which also included his father’s unspecified cancer diagnosis and separate prostate treatment, William has attended few events.

He spoke earlier this month at a charity event in London to raise money for London’s Air Ambulance Charity’s new helicopter fleet.

Christopher Nolan’s epic biopic of atomic bomb maker J. Robert Oppenheimer is expected to be a big winner at the Baftas after Oppenheimer received 13 nominations.

William has been president of Bafta since 2010 and Kate first attended the event with her husband in 2017.
