Bluebell is Geri's first child with screenwriter Sacha Gervasi. She has a son, four-year-old Monty, with husband Christian Horner, who she married in 2015.
The couple married in a star-studded ceremony in Bedfordshire on 15 May, one day after Bluebell's birthday, with a ceremony at St Mary's Church in Woburn, before hosting their reception at nearby Woburn Abbey.
