Ed Sheeran made his Game Of Thrones cameo in the first episode of the penultimate series.
The pop star sang during his fleeting appearance in the death-filled episode titled Dragonstone, which kicked off season seven when it aired in the early hours of Monday.
The 26-year-old was dressed as a soldier and singing around a campfire when he caught the attention of Maisie Williams's Arya Stark as she rode through a forest on horseback.
Stark told Sheeran's unnamed character: "It's a pretty song, I've never heard it before."
"It's a new one," Sheeran replied.
The singer-songwriter celebrated his appearance, posting a shot of his performance on Instagram after tuning into the show.
"Throwback to the time I was a Lannister," he wrote.
Fans praised Sheeran on social media.
Nadine tweeted: "How awesome is @edsheeran in that scene with Arya Stark?"
Lyndsey Vanstone added: "Amazing cameo from @edsheeran in @GameOfThrones season 7 premiere!"
The show's creators David Benioff and DB Weiss announced the singer would make an appearance as they spoke at a panel at South By Southwest Festival in Austin, Texas.
The HBO series based on George RR Martin's A Song Of Ice And Fire novels will reach its conclusion in the final season next year.
The show has scooped 38 Emmy Awards, more than any other narrative show.
