Prince Harry’s ex-girlfriend Cressida Bonas, 35, stuns in a burgundy dress with thigh-high split at a very lavish Venice wedding

Cressida Bonas cut an elegant figure on Saturday as she attended billionaire David Winter’s wedding to Georgia Irwin in Venice.

Prince Harry’s 35-year-old ex-girlfriend was caught leaving the Gritti Palace Hotel on Venice’s Grand Canal to board a boat to reach the lavish wedding ceremony on the island of Le Certosa.

The actress wore a shimmering bronze one-shoulder dress with a daring thigh-high slit.

She added even more glamor to her look with a delicate necklace and a pair of gold earrings.

The mother-of-one, who welcomed her son Wilburn in 2022 with husband Harry Wentworth-Stanley, styled her blonde locks and bangs in the perfect blow-dried ’60s style for the occasion.

The 35-year-old was caught leaving the Gritti Palace Hotel by boat to travel to the exclusive wedding destination.

Princess Eugenie introduced Cressida to her cousin Prince Harry, and they dated between 2012 and 2014, with Eugenie and the mother-of-one remaining close after their breakup.

Standard Industries CEO David’s wedding took place on the nearby island of La Certosa, with guests and their cocktails taken to the chic venue by water taxi.

La Certosa is an island in the Venice Lagoon, 500 meters northeast of Venice.

Before arriving at the star-studded ceremony, Cressida appeared cheerful as she greeted the other attendees.

Other guests included Sienna Miller, who put on a dashing show in a silk dress with her partner, Oli Green, 27.

After giving birth, Cressida’s mother revealed that she movingly named her son after her husband’s late brother, who died at the age of 21.

She has since been snapped walking around London with her son, dressed in casual clothes.

The 33-year-old welcomed her first child with husband Harry Wentworth-Stanley in 2022, after the couple married in 2020.

The couple chose to name him after Harry’s brother James, who committed suicide in 2006.

Sources told the Daily Mail’s Richard Eden that the name Wilbur James Wentworth-Stanley is a “dedication” to the 21-year-old.

Cressida, who dated Prince Harry for a while and was a guest at his wedding to Meghan Markle, has previously written about the impact of James’ death.

In 2022, she wrote in the Daily Mail that his death had turned the lives of her future in-laws “upside down.”

Elsewhere at the lavish wedding, Sienna Miller looked sensational as she attended with boyfriend Oli Green.

Sienna, 42, welcomed her second child – first with Oli – in January, a baby girl whose name they have not revealed, going braless for the occasion under a deep orange dress.

Sienna’s silk dress hugged her gorgeous curves and she completed the look with a chunky gold choker and matching bracelet.

The stunner, who already shares 11-year-old daughter Marlowe with ex-partner Tom Sturridge, added extra height to her frame with a pair of strappy sandals and stashed her day essentials in a chic clutch.

Meanwhile, Oli, 27, cut a dapper figure in a dark tailored suit worn over a crisp white shirt and emerald green tie.
