Sophie Turner dons 'just married' sash as she and Joe Jonas touch down in LA ...

They shocked fans as they tied the knot in a surprise Las Vegas ceremony which costed just $600.

And Sophie Turner and Joe Jonas already looked to be in the honeymoon phase.

The 23-year-old Game Of Thrones actress proudly wore a 'just married' sash as she and her new 29-year-old husband arrived back in Los Angeles on Thursday.

The happy couple traveled in style as they touched down on the runway aboard a private jet.

This came just hours after   DJ Diplo, 40, took to his Instagram Story to share videos of the nuptials which took place hours after the 2019 Billboard Music Awards were held in the same city and saw the Jonas brothers perform. 

In the clips, Joe, 29, is seen waiting at the altar before Sophie, 23, enters and walks down the aisle in a white veil and jumpsuit and gold Gucci mules.

The celebrity couple, who started dating in 2016, and announced their engagement in October 2017, tied the knot in front of loved ones and fellow Billboard Music awards attendees. 

Joe, who rose to fame with his family's band the Jonas Brothers, had previously said that the couple would marry in France, so it's likely that they will have a second ceremony this summer.  

Their ceremony in the Vegas chapel was presided over by an Elvis impersonator. In one clip, Sophie repeats  the words: 'I thee wed.... and I love you... and I thank God He gave me you.'

Then the couple, at Elvis's direction, repeated to each other in unison: 'I promise you, I will never leave you. I will love and trust you all the days of my life.' 

Elvis then instructed Sophie to kiss the ring, but as it was a candy ring, she decided to give it a big lick, which amused Joe immensely. 

Elvis then told Joe: 'You may kiss the bride', which he did as the guests whooped and hollered. 

Country stars Dan and Shay played their hit Speechless during the ceremony, singing the lyrics: 'It started when you said hello/Just did something to me/And I've been in a daze/Ever since the day that we met.

You take the breath out of my lungs/Can't even fight it/And all of the words out of my mouth without even trying.' 

Diplo played tunes from his deck and he filmed Sophie as she walked into the venue, then he took a sneaky snap of her as she was walking down the aisle.  

Much to the delight of fans, he filmed the moment that Joe saw Sophie walk down the aisle for the first time and he had a beaming smile on his face. 

The acclaimed DJ wore a white T-shirt tucked into jeans with a country-style belt, earlier protesting why he himself hadn't found love, writing on social media: 'How do I look this good and yet I am still single?'  

The couple were first pictured together at the MTV EMAs in 2016, where the couple were pictured sitting in the audience with their arms around one another.

Sophie, who has played Sansa Stark in Game of Thrones for eight seasons, confirmed she was dating Joe in January 2017, when she shared an Instagram picture of the Camp Rock star smoking a cigar while on a boat. 

In May 2017, the couple both attended the Met Gala together, but arrived separately and were not pictured together at any point. 

In March of this year, Sophie joined the other Jonas wives when they all appeared on the boys' comeback single, Sucker. 

Sophie briefly discussed how she and Joe first got together in an interview with Harper's Bazaar. 

She said: 'We had a lot of mutual friends, and they’d been trying to introduce us for a long time. We were following each other on Instagram and he direct-messaged me one fine day, out of the blue.' 

Meanwhile, the actress spoke of her love for Joe during an interview with Glamour magazine back in March. 

She said: 'A lot of [my happiness now] is to do with being with a person I’ve fallen in love with, who loves me more than he loves himself, and who wants to see me find my own happiness. 

'That was probably the biggest thing that pushed me to find who I am – and find my happiness in things other than acting.' 

Sophie also spoke to Rolling Stone about how she felt ready to become engaged to Joe when she was just 21 years of age.    

She told the publication: 'I was fully preparing myself to be single for the rest of my life. I think once you’ve found the right person, you just know.  

'I feel like I’m much older a soul than I am in age. I feel like I’ve lived enough life to know.' 

Sophie also spoke about her engagement with Marie Clare and said that while it's 'lovely' to be engaged, she considers her career to be her greatest achievement. 

She said last year: 'There’s this weird misconception that being married is the greatest thing that’ll ever happen to you. 

'But I’ve always found that my career is something I work for, and when I achieve something, there’s a sense that this is the greatest thing I’ll do in my life.' 

The couple's quickie wedding is in stark contrast to the four-day extravaganza in India last December when Joe's brother Nick, 26, tied the knot with Priyanka Chopra, 36.

However, Joe and Sophie have always maintained they wanted a more low-key intimate affair.

Priyanka, who has become close friends with the British actress, served as maid of honor at the wedding and the two were seen hugging each other right after Joe kissed his bride.

Joe had said that he and Sophie had learned a lesson from Nick and Priyanka's wedding in that despite the lavish nuptials, they had run out of beer. 

He told the Zach Sang Show: 'I mean, we are getting married in France, so a lot of Coors Light is necessary. Not hard, really, to get that, but we needed to make sure that was going to happen.'

Nick concurred: 'We learned a lesson from my wedding. Our friends drink a lot of beer, specifically, and we ran out of beer at the wedding, at my wedding, which was a big issue.' 

Joe and Sophie said their 'I do's' at the famous A Little White Chapel located in the Downtown stretch of the Las Vegas Strip.

Famous for its 24-hour Tunnel of Love drive-thru weddings and its pink Cadillac, the couple opted for a ceremony in the Chapel L'Amour with a package deal that runs around $600.

Later, photos of the newlyweds posing on the hood of the pink Caddy were shared via social media. 

Other notable couples who have eloped at the same Vegas venue include Bruce Willis and Demi Moore, Frank Sinatra and Mia Farrow, Paul Newman & JoAnn Woodward and Rita Hayworth & Dick Haymes.
