There were reports that the singer-turned-fashion designer Beckham has told friends that she never wants to sing again, ruining rumoured plans for another Spice Girls tour, reported Daily Star.
"It seems there are some very peculiar stories in the press today. I haven't seen one that's true yet!," Chisholm posted on Twitter.
Late last year, Chisholm, 39, spoke out to deny reports that the band was looking for a singer to replace Beckham. The five-piece last performed together at the Closing Ceremony of the London Olympics last summer.
