Ed Sheeran has walked away from his Twitter account with fans speculating that the backlash he has received for his Game of Thrones cameo may be the reason.

The singer-songwriter had deleted the account earlier on Tuesday but it is currently online with tweets ending in April 2015.

Sheeran's description on the page reads: "I don't use this anymore, please follow me on @teddysphotos on instagram, lots of love x."

The Castle on the Hill star took his Westeros bow as a soldier in the opening episode of season seven of Game of Thrones on Sunday night in the US and, inevitably, the slings and arrows followed.

Sheeran's cameo consisted of two lines:  "It's a new one", in reference to a song that Arya Stark (played by Maisie Williams) heard him singing; and his description of King's Landing as "Worst place in the world".

Some fans of the HBO fantasy phenomenon felt that Sheeran's presence distracted from the story and were less than complimentary about his acting abilities, but others came to his defence.

Sheeran recently told British newspaper The Sun that he had "come off Twitter completely" following the abuse he had received online.

"I go on it and there's nothing but people saying mean things. Twitter's a platform for that," he said.

"The head-f*** for me has been trying to work out why people dislike me so much."

Prior to deleting his account, updates on Sheeran's Twitter page had been automatically generated from his Instagram account - a platform he is still using. 

In other Sheeran cameo news, he is voicing the character of a musician on The Simpsons.

Entertainment Weekly, which first reported the story, says Sheeran's character, Brendan, will star in the episode Haw-Haw Land in the upcoming 29th season and will be a love interest for Lisa.

"He keeps alternating [between], 'You're not that great, but you could be fantastic', and she keeps falling for him because of his talent," The Simpsons executive producer Al Jean told Entertainment Weekly.
