On Thursday evening, she headed out to watch the England women's team take on Brazil, and she was joined by some surprise guests, including Lioness Beth Mead and her former Spice Girl co-star Emma Bunton, who was affectionately known as Baby Spice.
Geri was dressed beautifully for the snap in her signature colour of white, rocking a beautiful coat and turtleneck jumper as she embraced her fans.
Showing her support for the England squad, the mum-of-two referenced the iconic song Sweet Caroline as she wrote: "Come on England… reaching out!"
Fans loved Geri's unexpected reunion with Emma, as one enthused: "When Spice Girls get together the world feels a little better."
A second added: "Geri and Emma name a better duo!!!" while a third shared: "Spice plans on the horizon?" and a fourth commented: "Beth! Another Sporty Spice!"
Emma and Geri are very close and last year in an interview with the Daily Mail, Baby Spice opened up about the incredible bond she shares with her co-stars.
"Nobody else will ever understand that relationship between us," she told the publication. "We've been through so much and we still go through so much, from children to work. There's a bond there and it's very, very strong."
Although Geri is known for her love of white, she stunned fans when she headed to the Cheltenham Races last month where she had an alteration to her wardrobe.
Although she had a white top on, the singer was snapped while wearing a brown overcoat while watching the proceedings.
Fans were shocked by her change to her fashion, as one enthused: "What! There is no white!" while a second loved the change as they beamed: "Not wearing white."
Others were transfixed by Geri's beauty as one follower observed: "Beautiful picture Geri you look amazing," and another added: "Lovely to see a naturally beautiful woman."
