Sanna said in a statement: "I have long dreamed of going to Portugal and I'm a big Eurovision fan. It was really fun to commentate on Eurovision 2015 when Måns Zelmerlöw won. So when Edward rang, I didn't want to miss out. Sitting in a hot and crowded booth, having snacks and laughing at Edward will be great fun."
