Gwen Stefani fizzing with energy as No Doubt tour starts

P Diddy and Tiger Woods were in the audience as Gwen Stefani took to the stage with her No Doubt colleagues for the first time in five years.   

"You always remember your first show of any tour," the pop princess told fans a few songs into the concert, "and so far, so, so, so good."

Effervescent Gwen, who's had two boys since the band last performed together, has explained they don't yet have any new material. Playing live is a away of getting inspired creatively again, she added.
