Garth Brooks' special comeback event proves that this country superstar definitely has a powerful international standing -- he just sold out all five dates!

The singer added a fourth date just a few days ago. It went on sale Thursday morning (Feb. 6) and sold out in a hurry, so to keep up with the demand, a fifth date was added -- and every single one of those tickets was scooped up, too.

Fans who nabbed the tickets definitely put in the effort. Some eager ticket buyers braved the awful weather conditions, sleeping outside of Ticketmaster locations for three whole nights. Talk about commitment!

All 400,000 tickets for Brooks' event taking place at Croke Park in Dublin, Ireland have been spoken for now. This summer will be the first time any artist will play five consecutive shows there.

In addition to selling out Croke Park five times, concert promoter Peter Aiken admits, “In 52 years of business, this is the fastest selling concert Aiken Promotions have ever been involved in.”

The Garth Brooks Comeback Special Event will take place on July 25-29, 2014. After that, the country icon will be embarking on a world tour, which he announced earlier this winter on 'Good Morning America.'
