Ireland is preparing for the lavish wedding of Andrea Corr of the famous Irish pop group The Corrs, and Irish megaband U2 is set to play the reception.

The youngest member of the Irish family band will wed Brett Desmond, the son of Irish billionaire Dermot Desmond, on Friday at the Doonbeg Golf and Spa resort in County Clare. It is rumored that the wedding ceremony will take place at the scenic Seafield Church near Quilty.

U2 has been slated to perform at the couple’s reception. Corr and Bono are close friends, and performed a famous duet together, singing a version of “When the Stars Go Blue” to promote the Make Poverty History campaign. The two were even rumored to have an affair.

Two marquees have been erected at Doonbeg ahead of the Irish wedding, and the resort has already heightened security. Two men are keeping watch on the resort’s grounds, using binoculars to monitor the movements of reporters.

The Doonbeg staff has been sworn to secrecy, and club members have been told to stay away on the day of the wedding.

Desmond and Corr became engaged during a trip to Barbados last Christmas when the businessman slipped a €70,000 on the Irish singer’s finger.

Andrea Corr is the second member of her famous Irish family to wed in County Clare. In 2001, her sister, Sharon, married Belfast lawyer Gavin Bonner in Cratloe and hosted a reception at Dromoland Castle.
