WT-! So This Happened…Joe Jonas and Sophie Turner married by Elvis impersonator in Las Vegas.

Surprise — they’re hitched! Jonas and Turner married on May 1 in a surprise ceremony in Las Vegas following the Billboard Music Awards, where the Jonas Brothers performed at their first awards show as a band in a decade.

The ceremony, which was documented on Diplo’s Instagram live feed, was officiated by a lively Elvis impersonator at Chapel L’Amour inside A Little White Wedding Chapel, and included Joe’s brothers Nick and Kevin as groomsmen.

According to online records, the couple applied for a marriage license earlier in the day in Clark County, Nevada.

The singer and the Game of Thrones star recited vows at the prompting of the Elvis impersonator, holding hands and looking into each other’s eyes as they said, “I promise you, I will never leave you. I will love and trust you, all the days of my life. In sickness and in health… forever and ever.”
