Pippa Middleton confirmed she’s engaged to beau James Matthews by stepping out of her London home Tuesday morning flashing her huge diamond ring. The younger sister of Kate Middleton was photographed with a broad smile plastered across her face as her new sparkly piece of jewelry sat snuggly on her finger.

According to Cosmopolitan UK when paparazzi asked Middleton how she was feeling she responded that she “couldn’t be happier.” In the photos, Middleton’s ring features a large asscher-cut diamond in the center surrounded by smaller diamonds. High-end jeweler Neil Geddes told the Daily Mail that the ring is similar to an art deco piece but a lot more contemporary. “It was likely to have been made bespoke especially for her from Bond Street,” he said. “It sits fairly high on her finger allowing as much light to enter the diamond as possible and reflect back giving stunning brilliance and fire.”

News broke Monday that Middleton was engaged after she was spotted at a charity fundraiser for the British Heart Foundation with her left hand conveniently hidden from photographers. The BBC reported that Matthews, 40, proposed to Middleton, 32, Sunday during a romantic trip to the Lake District in England.

“The Duke and Duchess of Cambridge are absolutely delighted with the news,” Kensington Palace said in a statement Tuesday. Middleton’s parents Carole and Michael Middleton are also thrilled by the engagement news saying in a joint statement that Matthews and their daughter make a “wonderful couple.” Carole and Michael added: “We wish them every happiness together.”

Middleton and Matthews first dated in 2012 but split that same year. The Vanity Fair contributor went on to date Nico Jackson for three years before ending the relationship in 2015. Three months after her breakup from Jackson, Middleton and Matthews rekindled their romance. The pair is set to marry next year.
