Aiken Promotions says both Croke Park dates for Bruce Springsteen are sold out.
The US performer added an extra Dublin date for Sunday May 29th.
Tickets for both concerts went on sale from Ticketmaster at 9.00am.
Hits such as 'Born In The USA' and 'Dancing In The Dark' cemented him as one of America's top popular rock vocalists.
Springsteen was inducted into the Rock & Roll Hall Of Fame in 1999.
He has won numerous Grammy and Golden Globe Awards, while continuing to sell-out shows the world over.
Away from his on-stage commitments, he is an activist for equal rights and runs a charity called 'The Foundation' - which helps support war veterans and food banks.
These people queuing in Dublin spoke to Newstalk.com's Henry McKean earlier.
