Joe Jonas and Sophie Turner tied the knot in a surprise ceremony in Las Vegas, complete with an Elvis Presley impersonator as an officiant. 

Jonas, 29, had just performed at the Billboard Music Awards, where Turner, 23, was a presenter. They were spotted holding hands as they left the awards show early en route to the Little White Wedding Chapel.

Turner sported a white jumpsuit for her wedding day. Afterward, they celebrated by posing on a pink Cadillac. 

They also snapped a photo with Elvis and the two other Jonas brothers. 

The newlyweds topped off the night with a Jacuzzi dip in their wedding clothes. 

Turner, who plays Sansa Stark on "Game of Thrones," and Jonas announced their engagement in 2017.
