The blogger got engaged to boyfriend of five years David Fitzpatrick last week, when he dropped to one knee after writing 'Marry Me' in seashells on the sand in the Algarve.
The couple have enjoyed a week of celebrations since revealing their newly-engaged status, returning home to Ireland for a 'last minute' engagement party with friends and family in Dublin.
"I think it's safe to say both our families and friends are thrilled' the Instagram star captioned a video of the party, "So much love and happiness in the room, I can't even imagine what the wedding is going to be like."
Although they appeared to be enjoying the company of their close friends and family at home, the happy couple were quickly on a plane again to continue their celebrations, with Terrie posting some stunning snaps of the couple in sunny Madrid.
"I think we're really milking these celebrations now," the stylish bride-to-be jokingly captioned one image, and admitted: "I don't think I'm ever going to get used to the word 'fiancé," in another.
They've been enjoying the sites in the Spanish city including the Egyptian Temples and Retiro Park, which have been providing a beautiful backdrop for some of Terrie's sartorial snaps.
As they say; When in Rome - or Madrid!
