"They knew they needed to have a legal ceremony in the U.S. and decided a few weeks ago to do it in Vegas after the Billboard Awards," a source tells E! News. "Some of their friends and family would be there so it felt like the perfect timing."

"They booked the chapel for a big block of the night to make sure they had it to themselves and that the timing could be spontaneous," the insider continues. "A friend paid and set up the entire thing."

Congratulations, Mr. and Mrs. Jonas!
