In 1994 five girls answered an advert in The Stage newspaper for a new girl band. 25 years later, those five girls headline Wembley Stadium, for the third night in a row! Never in my wildest dreams could I have imagined that all these years later we would be playing to sold out stadiums, performing what I believe to be the best show we’ve ever done. It’s an honour and a privilege to share a stage with my fellow Spices, @therealgerihalliwell @officialmelb @emmaleebunton and the gorgeous @victoriabeckham will always be missed (hopefully someday to return)! I never forget though, none of this would have been possible without you – the unbelievable fans. You have made a very normal girl feel incredibly special and I can never thank you enough for this. I love you all and thank you from the bottom of my heart for allowing me to live this amazing life.

Earlier, Melanie Chisholm, or Sporty Spice, posted a picture of the group in their early days with a message to the absent Beckham.

She said: “The gorgeous Victoria Beckham will always be missed (hopefully someday to return)!”

Hollywood star Emma Stone is among a clutch of stars to have attended the concerts.

Adele herself is no stranger to Wembley Stadium, having played there a number of times.

In 2016 she was forced to pull out of two performances at the west London venue after damaging her vocal cords.

However, avid fans still gathered outside the stadium to perform renditions of her songs in an event titled Sing for Adele.
