In one of the videos, the DJ films Turner and Jonas entering a building with a group of people, the Game of Thrones star dressed in a white, strappy jumpsuit.
"Gonna hit this wedding real quick," the caption on the video reads.
Turner and Jonas are then filmed saying their "I dos" in front of an intimate room of people.
In true Las Vegas fashion, the videos show the ceremony being officiated by an Elvis Presley impersonator.
Turner wore a white veil to accompany her jumpsuit, while Jonas wears a grey suit with a boutonnière.
After exchanging their vows, the couple kiss as their guests at the lavish bash applaud.
They and the Presley-lookalike then dance in celebration of the event.
The 23-year-old actor and the 29-year-old singer announced their engagement in October 2017.
Several fans of Turner and Jonas have expressed their excitement over their apparent marriage.
