Generation X and Millennials, get ready to have the SPICE smacked into your soul.

The Spice Girls are reuniting as a five-some.

YES, Victoria Beckham has finally agreed to rejoin the girl group that made her a superstar in the 90s.

However, she’ll only resume her role as “Posh Spice” for one night only.

It’s been reported Geri Horner (Ginger Spice), Mel B (Scary Spice), Mel C (Sporty Spice), Emma Bunton (Baby Spice) and Victoria will reprise their spice identities at Geri’s birthday bash.

The oldest Spice Girl will be turning 50-years-old on August 6 and will be throwing a massive party to celebrate in September.

Per reports, Ginger has enlisted the help of her former bandmates to take part in their first performance together in a decade.

A source revealed to The Sun, “The girls can’t wait to reunite and the plan is for all five of them to sing Happy Birthday and get up on stage to join Geri for a number — possibly ‘Wannabe.’”

“They all want to mark the occasion in style, and reuniting after a decade seems the perfect time,” the source continued.
