Most of us have been singing some variation of "ha, see ya, hold tight" since the hit track was first released in 1997, which makes this revelation all the more confronting.
(By the way, "hai", "si" and "ja" are the Japanese, Spanish and German words for "yes" — so the Spice Girls are basically saying "yes, yes, yes, hold tight!")
Here's the video, in case you now want to have a go at singing along using the correct lyrics:
Earlier this week, the Spice Girls sent fans wild over the announcement of their long-awaited tour with a tongue-in-cheek video.
In the clip, the band members jokingly bickered over their outfit choices — seemingly in a nod to Geri's refusal to adhere to the all-black dress code at a press conference back in 2007 — before breaking into an a cappella version of Spice Up Your Life.
Sadly for Aussie fans, there are currently only six shows scheduled — all in the UK. However, Mel B hinted on British panel show Loose Women that she and her fellow bandmates would like to expand their performances.
Asked if she'd like the band to go on a world tour, she responded: "We are. The hopes are that we go everywhere else in the world, but right now it's just the UK."
