Sharing a snap of her latest outfit – a pretty pink pinafore dress – the former Spice Girls star wrote: "Made a big mistake today, my dress is too short! Gonna keep my coat on," followed by a laughing emoji.

She continued: "It was at their house but apparently we were in the stables! You didn't know that did you? Apparently, the whole setup was in the stables, so I said to Christian [Horner] 'ooh how did you get rid of the smell of the horses?' because it was gorgeous, so there was a whole scent thing going on and it was beautiful. It was really good fun, it was good to see Geri having a blast at her 50th – she'll hate me saying that."
Earlier this month, the news of their reunion went viral after David Beckham posted a video of the quartet dancing to their 1996 hit song 'Say You'll Be There.'
