The Spice Girls have denied reports they lip-synced their way through the opening night of their world tour in Vancouver, Canada, on Sunday, insisting it was all live.

The reformed five-piece wowed the sold-out crowd of 16,000 with hit after hit, but were accused by some critics of actually miming to a backing track.

However, a spokesperson for the group has dismissed the criticisms, saying, "All of the girls sang live.

"There is a click track for the band to keep them in time, which is standard, but all of the girls' vocals were live."

The next stop on the Wannabe hitmakers' global tour is in San Jose, California on Tuesday.
