In light of Scary Spice’s absence, Beckham sent the star a heartfelt message on Monday via her Instagram Stories telling her how much they missed her on the night.
Sharing part of the video on her Story, the 48-year-old penned: “When the @spicegirls reunite for one night only (minus Scary Spice! We miss you @officialmelb!!)
“Love you girls @therealgerihalliwell @emmaleebunton @melaniecmusic xx.”
All five members were originally reported as expected to be reuniting for the milestone occasion. Instead, Mel B opted to stay at home and celebrate her recent engagement to hairdresser Rory McPhee, while enjoying bonfire night with her loved ones, according to family tradition.
Mel B’s representative told the Standard: “Melanie attended her family’s annual bonfire night event, which was also to celebrate her engagement to Rory – but she had a long chat with GerI before the party.”
Horner spared no expense on the lavish party and, according to the Sun, dropped a whopping £400,000 on the bash. She officially turned 50 in August and had planned for the party to take place in September, but decided to postpone it because of the Queen’s death.
Entertainment was provided by Dame Shirley Bassey, 85, who belted out Happy Birthday.
Former The X Factor winner Alexandra Burke is also believed to have performed. Others in attendance were TV presenter Rylan Clark, who shared a group picture with Horner, her husband Christian, daughter Bluebell, 16, whom she had with director and screenwriter Sacha Gervasi, plus her bandmates.
The star-studded guestlist included Myleene Klass, Poppy Delevingne, Chris Evans, Holly Willoughby and Zack Ashley.
According to the publication, Christian made a heartfelt speech at the party and was also snapped lovingly slow dancing with his wife on the dancefloor.
