Such is the demand for Russell Brand's future first-lady, her current tour has just been effectively doubled up for a second wave of concerts later next year. Katy Perry's world domination continues with yet more UK concerts planned for the tail-end of next year - considering the first-leg has pretty much sold-out, you might be keen to get in quick for this dirty dozen!

The opening night for the second leg is in Sheffield on 12th October, followed by an O2 Arena gig on the 14th plus more in the usual big cities such as Liverpool, Newcastle and Nottingham, before rounding it all off in Dublin on 7th November. Tickets for this follow-up round of the "Californian Dreams Tour"go on sale from this Friday at 9am, with prices similar to the sold-out leg (upwards of £27.50).

Her 2010 album has also been steaming, sales-wise, around the globe, including Australia where she has stormed the number one spot and increased her tour by another half-dozen gigs or so. You get the feeling this woman hasn't even started yet...
