Spice Girls have broken ticket sales records that fans fought to secure their place at a show in an online queue of more than 700,000 people.
The band added a series of dates to their meeting tour after the fans waited their frustration in the rush for tickets.
The group, who will be back along the way next year without Victoria Beckham, announced that they will play extra dates in London, Coventry and Manchester.
The Spice World tour will now kick at the Etihad Stadium in Manchester on May 29, 2019, instead of June 1, and they will play three dates in the city.
They will play another two dates at Wembley Stadium in London with exhibitions on June 13, 14 and 15 and an additional date in Coventry, with another show at the Ricoh Arena on June 4th.
Andrew Parsons, CEO of Ticketmaster, said: "The demand for Spice Girls was out of the table. They have broken through Ticketmaster UK's registry to be the busiest ever-selling.
"There were millions of people on our side looking for tickets, with a queue at a point of over 700,000.
"Hundreds of thousands of tickets were sold to happy fans all over the country within minutes. Congratulations to the girls. From what we saw they could have played almost every night for a year."
The fans fought to secure tickets for live shows, which resulted in Ticketmaster writing on Twitter: "Morning Spice fans! It's a very busy morning and we sell tickets fast.
"To ensure fair access, some of you may see queues, follow the instructions."
A fan wrote on Twitter: "@TicketmasterUK how can someone buy tickets to # SpiceWorld2019 when" something went wrong "continues to show ????? Absolutely ridiculous!"
Another said: "No @TicketmasterUK, there is no problem with my connection! Your site can not handle the Cheers #igiveup traffic."
Others expressed anger that tickets were already on resale sites. You wrote: "Absolutrubbish. Continue to be kicked. Somehow, these tickets are already on other sites for hundreds already."
Another said: "@TicketmasterUK You're joking with me, I've been in the queue since they went for sale, keep getting the error and people have already bought them and put them on stubhub for a RIDICULOUS amount of money. Come and put it out. "
Others, however, celebrated their success with a fan who said: "GUESS WHO GETS TO # SPICEWORLD2019 NEXT YEAR !!! I cry literally. Dream come true."
Another wrote: "Can not believe I got tickets !!! So so soooooo excited! Ha-Si-Ya HOLD TIGHT !!!!"
Ticketmaster praised fans and urged them not to give up, tweeting: "The place is humming and lots of you get your @SpiceGirls tickets here this morning!
"If you're still in the queue do not worry, there are plenty of tickets to go around."
