Another concert stakes its claim for the "fastest selling concert ever", with both of Britney's Irish dates selling out this morning within minutes.

Fans reportedly queued all night outside Ticketmaster outlets around the country, battling sub-zero degree temperatures for the chance to see Spears' debut Irish jaunt. Such was the demand that a second Dublin show, June 3, was added on the spot. Tickets were snapped instantly by the frenzied, no-doubt frost-bitten, fans.

Britney brings her Onyx Hotel Tour to the Odyssey Arena in Belfast (June 1) and The Point, Dublin, June 2 and 3.
