According to Joe and Sophie's official marriage license, Sophie changed her name from Sophie Belinda Turner to Sophie Belinda Jonas after tying the knot.
According to court documents, they applied for the marriage license the morning of their wedding day.
Their officiant, Jesse Grice (the amazing Elvis impersonator) told TMZ that the pair booked the venue, the Little White Wedding Chapel, one week in advance.
Their family including Nick and Kevin, plus some celebrity friends headed to the Vegas chapel following the Billboard Music Awards yesterday.
Congratulations to the happy couple!
