The couple hit the fabled Little White Wedding Chapel with family and friends after the Jonas Brothers' comeback performance at the Billboard Music Awards, and sources insist the celebrations are likely to last a few weeks as there's another bash planned in Europe.
"Joe and Sophie are a couple that loves to have fun and live in the moment, and that's exactly what getting hitched in Vegas was," the insider tells Entertainment Tonight. "The couple does plan to have a more formal wedding with their family and friends, but this ceremony was just fun. Joe and Sophie are planning to get married in Paris later this year."
"I don't know why she's thinking about that (what she's wearing to my wedding); I'm giving her the bridesmaid dress!" Sophie said about Maisie's role at her wedding on the red carpet at the "Game of Thrones" premiere last month. "She's my maid of honour. One of two."
