The formerly brunette singer unveiled newly dyed blonde waves while posing backstage with Ginger Spice.
“Oiii last time I saw the Spice Girls at Wembley was 21 years ago! Tonight with my nearest and dearest I cried, laughed, screamed, danced, reminisced and fell back in love with my 10-year-old self,” Adele wrote on Instagram.
Adele added: "It’s no secret how much I love them, how much they inspired me to run for my life and never look back. I finally got to meet Ginger, I got drunk with the girls and quite frankly I can’t believe how far I’ve come 😂 thank you for the madness I get to live, I couldn’t have got here without you 5 BRITISH legends! I love you! ❤️"
Meanwhile, fans took to social media to gush over Adele's look from the night.
"Adele got that post divorce glo, she is coming y'all. She is coming for our wigs, stepping on necks. All of that," one Twitter user wrote.
"Adele is GLOWING," someone else wrote alongside the photo of the "Hello" singer with the Spice Girls.
"Adele has never looked better. Adele has never looked freer. Adele has never looked more comfortable with herself. There I said it," someone else said.
In April, Adele and her husband Simon Konecki confirmed their split after more than seven years together.
“Adele and her partner have separated,” the Grammy winner’s representative Benny Tarantini and Carl Fysh said in a statement to the Associated Press.
“They are committed to raising their son together lovingly. As always they ask for privacy. There will be no further comment.”
The 30-year-old singer (real name Adele Adkins) and entrepreneur-philanthropist Konecki, 44, have long stayed mum on the subject of their relationship. They welcomed their son Angelo in 2012 and confirmed she married Konecki when she won album of the year at the 2017 Grammys.
