Geri Halliwell and her husband Christian Horner are reported to attend the first day of Royal Ascot together. Multiple accounts describe the couple arriving at the Berkshire racecourse hand in hand as they take part in what is presented as a high-profile outing on the opening day of the event. One report specifically notes that Halliwell wears a bridal-style gown, drawing attention to her appearance as they arrive. The coverage frames the day as a star-filled start to Royal Ascot, with Halliwell and Horner among the notable figures present. Both sources provide the same core details: the location is Royal Ascot at the Berkshire course, the timing is Day One, and the couple appears together on arrival. No additional information beyond their attendance, their joint arrival, and Halliwell’s gown is included in the supplied summaries.
