Jonas Brothers' fans at their concert on Thursday were given a bonus treat when Sophie Turner made an impromptu appearance on the stage.
The band are currently in the midst of their Happiness comeback tour and played in Washington DC on Thursday, the same day that Joe Jonas - the middle brother - turned 30 years old.
In a video Joe shared to Instagram, brother Nick is seen leading a mass chorus of 'Happy Birthday' from the crowd while Sophie and Danielle Jonas appear on stage with a birthday cake, which they lit with help from Kevin.
After the crowd finished in the communal sing-a-long, Joe blew out the candles before giving his wife a thank-you kiss, much to the screaming crowd's delight, and then face-planting the cake.
'Couldn't have asked for a better night,' Joe captioned the adorable video on Instagram. 'Nothing better than doing what I love with my loves on my birthday.'
Earlier in the day, Sophie wished Joe a Happy Birthday on Instagram, calling him the 'the best thing that's ever happened to me' and then sharing a picture of them in a swimming pool.
Elsewhere on Joe's story was a picture of the incredible cake he was given on his 30th, showing him sat on the Iron Throne alongside his Game of Thrones actress wife, Sophie.
It's been quite the year for Joe. Not only did he reunite officially with his siblings to bring back the Jonas Brothers, release hit singles and embarking on a mammoth tour, he also married Sophie in a stunning ceremony in the south of France in July.
Happy birthday, Joe!
