Mel B jokingly slammed former Spice Girls Victoria Beckham and Mel C for not agreeing to the band's reunion.
The 41-year-old singer will be teaming up with Geri Horner and Emma Bunton later this year (16) to mark 20 years since the release of the group's debut single Wannabe.
Both Mel C and Victoria have turned down the chance to be part of the comeback, and as she appeared on The Late Late Show with James Corden on Thursday night (08Sep16), Mel B grabbed the opportunity to reveal her true feelings about her bandmates' refusal.
"The other two... didn't want to do it!" she said, to screams of laughter and shock from the audience. "No, let me correct that. My other two fellow lovely ladies... Victoria's busy with her great fashion line, Mel C is doing her own album, and so they graciously said, 'You three go ahead and do it!'
"We are girl power, we support each other, so we went, 'Ok, well let's just us three do it!'"
There had been rumours that the three-piece would be asking other music stars to stand in for Victoria and Mel C on stage. However, Mel B insists they would never be able to replace the duo.
"I don't think we could ever replace Sporty (Mel) or Posh (Victoria) but I'd like to invite some people up on stage with us, that would be great," she said.
When host James suggested Adele, who had already shown her love for the Spice Girls on his Carpool Karaoke segment, Mel replied: "I love her anyway!"
Mel C, real name Melanie Chisholm, recently penned an essay for Love magazine explaining her difficult decision to bow out of the "lucrative" reunion.
"I'd love to play huge arenas across the world, sing our brilliantly bonkers pop songs and relive our former glory," she wrote. "It is of course a very lucrative opportunity too. But we were a five-piece band. Didn't we reach a peak with the (London 2012) Olympics? There's a lot to be said for bowing out on a high note.
"For me, the absolute pinnacle of my Spice existence was being watched by a billion people around the globe belting out Spice Up Your Life on top of a black cab at the 2012 London Olympics. Anything less than the full line-up just didn't feel like we'd be doing justice to the band or the fans."
