Well, this was unexpected.

When pop star Joe Jonas (29) and 'Game of Thrones' actress Sophie Turner (23) announced their engagement in 2017, most people assumed that theirs would be a lavish showbiz wedding. However, it seems that the couple have tied the knot in a relatively low-key manner.

Jonas was performing at the Billboard Music Awards in Las Vegas last night with the Jonas Brothers, marking the trio's first performance at an awards show in ten years. Afterwards, ET report that he and Turner headed to a nearby chapel where they were married by an Elvis impersonator.

They were joined by a select group of friends, including Diplo. His Instagram story shows Turner in a veil and white silk trouser suit and Jonas in a grey suit, as country duo Dan + Shay provide the soundtrack.
