The wedding went down Wednesday night in Sin City immediately after the Billboard Music Awards, where the Jonas Brothers performed at the MGM Garden Arena.
DJ Diplo fired up a livestream on his IG Story and all of a sudden Jonas and Turner were seen at the Little White Wedding Chapel with an Elvis impersonator officiating their wedding. Brothers Nick and Kevin could also be seen standing next to their brother at the altar.
"Gonna hit this wedding real quick," Diplo casually revealed before the famous couple exchanged nuptials.
Jonas and his "Game of Thrones" bride may have surprised the world with their wedding, but they had planned to tie the knot because they applied for a marriage license earlier in the day.
Jonas and Turner announced their engagement in 2017 and have been inseparable ever since.
