The 41-year-old star said Victoria may have "secretly" asked for her microphone to be "turned down," reported ET online.
"She wishes it was turned off! We sung live, and we wrote and recorded all our music together live and we performed it live. It wasn't turned down. Not that I know of. Maybe she secretly asked for that - I don't know about that," Mel B said.
Singer-turned-designer Victoria Beckham recently revealed that her microphone was always turned off when she was performing on the stage with the other girls at Spice Girls' past concerts.
