Mel C, Mel B, Emma Bunton and Geri Horner all appeared in the minute-long clip which sees Geri miss the all-black dress code memo, opting for a typically sassy sequin number.
As they bicker amongst each other, they joke they can't be falling out so soon after announcing their tour.
They even give fans the iconic la la la's from their hit track Spice Up Your Life.
The girls will play six stadium shows across the UK next year with support from Jess Glynne, and tickets go on sale Saturday at 10.30am.
Kicking off at Manchester's Etihad Stadium on June 1, the group will call at Coventry's Ricoh Stadium two days later, the Stadium of Light in Sunderland on June 6, BT Murrayfield Stadium in Edinburgh on June 8, Bristol's Ashton Gate Stadium on June 10, and end on June 15 at London's Wembley Stadium.
Raring to perform together again, the girls can't hide their excitement.
Emma said: "It’s time to spice things up all over again!!!!! I can’t wait to perform to our forever supporting fans and a whole new spice generation! Love you all!”
Mel B told fans: “I’ve said it sooo many times I’m beside myself it’s actually happening yipppeeee. I’m now properly screaming it from every rooftop - me and my girls will see you all on stage!!”
Even Victoria Beckham, who's not part of the reunion, is supporting the girls, saying: “Being in the Spice Girls was a hugely important part of my life and I wish my girls so much love and fun as they go back on tour, I know they will put on an amazing show and the fantastic fans past and present are going to have a wonderful time!”
