Nicky Hilton looks stunning as she models a leopard-print swimsuit while on vacation in Costa Rica

Nicky Hilton Rothschild took this weekend off.

Paris Hilton’s 39-year-old sister was spotted in a sexy leopard print swimsuit during her tropical vacation with husband James Rothschild.

The two seemed to relax after she gave birth to their third child, a son, over the summer.

Hilton posted a carousel of photos at the luxurious, holistic wellness resort in the foothills of Costa Rica’s Cordillera de Talamanca mountains.

She spent time relaxing, surrounded by clear waters and lush greenery. In her caption, she revealed that the couple spent “72 hours in the lush tropical forest.”

At Hacienda AltaGracia, a property of Auberge Resorts, Hilton took part in a healing crystal sound bath, as evidenced by another photo posted. She also showed off a yellow floral swimsuit and full-body mud mask in another of the photos.

She was leaning on a daybed in sunglasses, a colorful striped hoodie and jeans. In other photos in the carousel, she posed in a long, flowing robe and maxi dress.

The American fashion designer, entrepreneur, socialite, model and philanthropist recently had a third child — their first son — with financier James Rothschild, 37.

She married the only son of the Mayor of Amschel, James Rothschild, in a nondenominational ceremony at The Orangery in Kensington Palace Gardens in London, England, on July 10, 2015, into one of the wealthiest families in the world.

The couple met four years earlier, according to The New York Times, at a wedding in Rome – after hosting Petra Ecclestone and James Stunt.

‘We didn’t meet’ [until] after the cocktail hour reception,” Nicky said in an interview with W. “I was standing there talking to my sister with a guy chatting with Paris. And [Rothschild] walked up to him and introduced himself. And I thought, ‘He’s cute too.’

‘And then we didn’t see each other’ [until] after dinner. I was living in LA at the time; he was in London. So it was about a year long haul LA-London.’

The couple share two daughters – Lily-Grace, six, and Theodora ‘Teddy’, four – and a son born in July. The parents have not yet revealed the name of their son.

On July 5, Hilton Rothschild posted a black-and-white silhouette photo of herself and her husband on her Instagram to announce an addition to their growing family.

“We’re officially a party of 5!” she wrote. ‘Welcome to the world my dear boy. Mom, Dad and big sisters couldn’t be more in love.’

The couple has not yet disclosed the birth details of their son. Although she has shared photos of the family in recent months, the parents are maintaining privacy and making sure not to reveal the son’s face yet.

In the summer, in the weeks following the birth of her son, Hilton was immediately throwing a summer dinner party to celebrate the release of her collaboration collection with shoe retailer French Sole. In the collection, Hilton Rothschild designed several animal print themed ballerinas.

Surprisingly given her eye for fashion, the capsule collection released in 2019 marked her first time designing shoes.

Late last month, she released another collection for the Nicky Hilton x French Sole collaboration that includes the zebra and leopard print ‘Paris’ flats, believed to be named after her older sister, Paris Hilton. The fashion designer never shuns animal print!
