Here's how the stars prepared for the beginning of the end of 'GOT.'

Joe Jonas whipped out his old Sansa Stark costume in celebration of Game of Thrones' season eight premiere on Sunday. 

The 29-year-old singer, who is engaged to GoT star Sophie Turner, couldn't help but honor the special day dressed as Lady Sansa. Hours before HBO aired Thrones' anticipated premiere, Jonas posted a video of himself posing to the sweet sounds of the show's theme song, wearing the Sansa Stark costume he sported on Halloween, red wig and all. 

"MOOD," he wrote alongside the video -- which received both laughs and praise from celebs like Priyanka Chopra, Julianne Hough, Ciara, Adam Lambert and more. 

As for how Turner prepared for the beginning of the end, the actress shared a special behind-the-scenes photo with her fans. "In honour of the final season of Thrones premiering tonight .... Here’s a picture of me asleep on set," she joked. 

Stars like Jimmy Kimmel, Jessica Chastain, Charli XCX and more also geared up for the season eight premiere of GoT on social media. Check it out below.
