'Game of Thrones' Season 8 Update: Dylan Sprouse Hints Playing Rhaegar Targaryen's Role, Sophie Turner Goes For Final Costume Fitting

Fans are not letting any single detail of Game of Thrones Season 8 slip without them knowing. In fact, aside from Sophie Turner's final costume fit, they also saw Dylan Sprouse's new Instagram post that sent them into a frenzy.

The former 25-year-old Disney actor shared a snap of himself while being surrounded by a group of people, who seemed to be fixing his looks. Surprisingly, he was wearing armor with a red cape that seemed to be from Game of Thrones.

The Suite Life of Zack and Cody star also seemed to be inside an old castle while he was donning a long blonde, braided hair. His followers can't help but thinking that he might be playing the role of Rhaegar Targaryen in Game of Thrones Season 8.

However, the role of Daenerys Targaryen's (Emilia Clarke) older brother was already played by Wilf Scolding in the previous scene, Pretty 52 reported. "Rhaegar Targaryen?" one of his Instagram followers asked. "New GoT actor????" another fan said.

Knowing that Jon Snow's (Kit Harington) true parentage is already revealed, it is quite expected that Rhaegar will be more visible in Game of Thrones Season 8. His and Lyanna Stark's storyline are assumed to be explored to tell more about of his secret second marriage and what really happened at the Tower of Joy.

Additionally, one fan even commented that Game of Thrones is getting mainstream, to which Sprouse replied with as if it is not that mainstream yet. With that, The Suite Life on Deck seemed to neither deny nor admit his involvement in the HBO's hit television series.

Meanwhile, in an interview with Coveteur, Turner talked about the imminent ending of Game of Thrones Season 8's filming and her recent costume fitting for the show. "There are moments it doesn't seem final," she revealed.

The 22-year-old star revealed that she went on her final costume fitting and said goodbye to her stylists. She described that they were seemed surprised not to seeing her again. To recall, she only had one new outfit donned in the previous season of the television adaptation of George R.R. Martin's A Song of Ice and Fire novel series. So, she had her costume fit before she started filming.

 Game of Thrones Season 8 is expected to return in 2019 on HBO.
