Peter Phillips’ first wife Autumn Kelly is expected to make a surprise move at her ex-husband’s wedding to NHS nurse Harriet Sperling at All Saints Church in Kemble next month.
Kelly is said to be among those invited to attend the ceremony, which will take place near Cirencester.
Her potential presence at the wedding will highlight the monarchy’s most successful examples of contemporary co-parenting after a high-profile separation.
Phillips and Kelly share two daughters, Savannah, 15, and Isla, 14. Her lasting connection to the royal family was evident earlier this month when she was seen enjoying moments alongside Princess Anne at the Cirencester Horse Trials.
The two appeared immersed in conversation while watching Zara Tindall compete at the event. The relaxed interaction highlighted the remarkably warm relationship Kelly, 48, has preserved with her former in-laws since splitting from Phillips in 2019, with their divorce finalized in 2021.
Princess Anne, 75, has maintained a particularly strong bond with her former daughter-in-law over the years.
Both have since found new partners, with Kelly enjoying a long-term relationship with Irish businessman Donal Mulryan. Earlier this year, the former couple attended the Cheltenham Festival alongside their respective partners, with the group appearing completely at ease throughout the race.
