Joe Jonas and Sophie Turner will ''potentially'' have a big party to celebrate their marriage.

The Jonas Brothers star and the 23-year-old actress tied the knot in a surprise ceremony in Las Vegas at the beginning of the month - just hours after the Billboard Music Awards - but have hinted that they will throw a lavish bash soon so that all of their friends can attend.

When Graham Norton asked if she and Joe are having a party to celebrate their wedding on 'The Graham Norton Show', Sophie replied shyly: ''Potentially!''

Graham gasped: ''Oh no, is that a secret? Not anymore. I didn't sign anything. It's in France, 15th of July...I have no idea.''

The 'Game of Thrones' star said with a laugh: ''That was a pretty good guess!''

The couple announced their newlywed status when Diplo took to social media to share clips of the ceremony, including the bride walking down the aisle in a white gown and veil, and country duo Dan + Shay performing their song 'Speechless'.

In the clip, Sophie said: ''I thee wed.... and I love you... and I thank God He gave me you.''

She and Joe also turned to one another and repeated: ''I promise you, I will never leave you. I will love and trust you all the days of my life.''

However, despite capturing everything on camera, Sophie and Joe didn't ask Diplo to film.

She explained: ''We didn't choose him to be our wedding photographer.

''He just kind of decided to live stream it.''

The wedding was officiated by Elvis Presley impersonator Jesse Grice but he had no idea his clients were celebrities until six minutes before the ceremony started.

He said recently: ''It was a total surprise. I recognised his name but without being a huge fan it wasn't nerve-wracking. We didn't get starstruck or anything like that. They were nice cool guys and real down-to-earth. They were into each other so much. I'm a Vegas man, so I give them 75-25 odds. That's good!''
