Most 21-year-old women know their way around a bottle of Clearasil, but we don't usually get to see acne on our pop stars.

So it's quite refreshing to see that X Factor winner Alexandra Burke doesn't mind being snapped without her slap on - even when it means the world can see her less-than-flawless complexion.

Alex was photographed as she arrived at her hotel in Dublin, and was happy to smile for the paps and fans waiting for her.

She's in Ireland to perform at the Cheerios Childline charity gig - a day after her own first headline gig was a success at London's atmospheric Union Chapel venue.
