Ronan Keating and Storm Uechtritz married on Monday
Other guests expected to join the newlyweds on their wedding day include Storm's family, who had flown over from Australia especially for her big day.
Ronan is a regular visitor to the estate in Haddington, East Lothian, and hosted a charity golf event there in May.
The beautiful bride is thought to have been escorted down the aisle by her father Gordon, with Ronan's daughters Missy, 14, and Ali, nine, joining the bridal party as Storm's bridesmaid and flower girl. Meanwhile the groom had an extra special best man on hand in the shape of his 16-year-old son Jack.
Ronan and Storm announced their engagement in HELLO! magazine
Fans began to guess that Ronan and Storm could be tying the knot this week after they both celebrated their hen and stag dos on Thursday. While Storm enjoyed a surprise trip to Paris with a group of friends and Ronan's daughters, Ronan gathered his closest friends and son Jack for a golf day in Stoke.
The newlyweds first started dating in 2012 after meeting on the set of The X Factor in Australia. Ronan, 38, proposed not once but twice earlier this year - first during a romantic holiday in Thailand and then again in Ireland in front of his three children. The happy couple announced their engagement exclusively in HELLO! magazine in April, with Love Me For a Reason singer Ronan saying it was "the most magical thing in the world".
