Spice Girls are officially back with a bang, as they kick off their reunion tour with major nostalgia.

Emma Bunton, Mel B, Mel C and Geri Halliwell kicked off their Spice World UK and Ireland tour in Dublin on Friday night, giving fans major '90s nostalgia. It had been seven years since they last performed together – including Victoria Beckham, who opted out of the reunion tour -- at the 2012 Olympics. Now returning without Posh Spice, the ladies treated fans to spectacular performances of their songs, including "Wannabe," "2 Become 1, " "Spice Up Your Life," "Viva Forever," "Goodbye" and many more.

In true Spice Girl form, the ladies brought the girl power with their greatest hits, dance moves and incredible statement outfits designed by Gabriella Slade.

Victoria opted not to join the band’s reunion tour in order to focus on her self-titled fashion brand.

The Irish capital has been buzzing ahead of the concert, with many taking to social media to say it was a moment they never thought they would never see.

However, a number of excited punters were left disappointed after “horrific” sound issues ruined their Spice experience.
