The star was spotted picking up some groceries in the store on Friday, before she later headed out to the Spice Girls gig with her pals at Wembley - doesn't she look lovely in her laidback outfit? "Thirteen stadiums. nearly 70,000 people, with three awesome women I've shared that stage with", she said.
The "Someone Like You" singer - and self-professed Spice Girls superfan - caught the group's last show of their Spice World - 2019 Tour Saturday at Wembley Stadium, and had a blast singing along and hanging out with the ladies after the show.
Geri said: "21 years ago, these girls did a great job and they appeared at Wembley Stadium".
Geri also shared a heartfelt video of herself standing inside the empty stadium following the final show.
"In second grade, did I go up to the teacher on the first day and ask her to call me Emma?"
Meanwhile, Horner posted an emotional video post-show in which she thanked everyone involved in the tour.
'Thank you for the madness I get to live, I couldn't have got here without you 5 BRITISH legends! "I finally got to meet Ginger, I got drunk with the girls and quite frankly I can't believe how far I've come". "I was a fiend, I was obsessed with the Spice Girls, they thought me about Girl Power", Stone explained to Graham Norton.
However Victoria dashed hopes she would make an appearance during the last night of the tour, as she was pictured arriving at Sergio Ramos and Pilar Rubio's wedding with husband David in Seville.
"I want to say thank you to Melanie, Melanie and Emma and everybody who showed up for us".
Reminiscing on the group's early days, Mel B wrote a post saying it as an "honour" to share the stage again with her fellow Spice Girls.
