Christina AguileraChristina AguileraIf you happen to see a teeny platinum blonde strutting down your local high street take a second look.

It may well be Christina Aguilera popping out for a pint of milk, as she's touring across the UK.

Xtina launched her Back To Basics world tour in Sheffield to a sell-out crowd.

We're fans of the songstress' 1920s image, so approve that this look inspired the show.

For those of you who couldn't get your hands on tickets, it seems like you're missing out...

Sorry to rub it in.

Newlywed Ms Aguilera recently celebrated her one-year wedding anniversary with husband Jordon Bratman in Dublin, Ireland.

But she proved she's still dirty with a number of raunchy performances, including Nasty Naughty Boy - involving whips. 'Nuff said.

Lady Marmalade and the classic Dirrty - which saw Christina don the now-iconic chaps and writhe around on a fairground carousel horse - were some of the favourites performed during the show.
