The 26-year-old "Galway Girl" hitmaker says he isn't worried about what other people think of his role.
"Last I'll say on this. I came off Twitter Coz I was always intending to come off Twitter, had nothing to do with what people said about my game of thrones cameo, because I am in game of thrones, why the hell would I worry what people thought about that. It's clearly awesome. Timing was just a coincidence, but believe what you want (sic)," reads a post on his Instagram.
"I think Ed did a lovely job - he's a lovely actor and a lovely person. He was appropriate for the part because he needed to sing. If people didn't know who Ed was, they wouldn't have thought about it twice.
