The DNCE frontman invited the 'Game of Thrones' actress - who he recently started dating - to the nuptials of his friends in Malibu and they shared a table with his brother Nick.

Nick shared some pictures of their entire table on Instagram and wrote: "About last night table 5 madness... #rp @pariscarney (sic)."

Joe, 27, and 20-year-old Sophie went public with their romance at the MTV European Music Awards in Rotterdam, Netherlands, on November 6.

In photographs, obtained by the Hollywood Life, the hunk was seen with his arm draped over the actress, while they gazed into one another's eyes at the glamorous event.

However, Joe's low-key date won't come as too much of a surprise to fans as he recently admitted that he enjoys getting to know new people in a mutual environment with some drinks.

He said: "I'd like it to be really low key. I think there's this thing that happens where, with a first date, there's just this immense amount of pressure on both sides that it just has to be kind of magical. But the whole purpose is to get to know somebody, get a vibe going and then, from there, you kind of decide, 'Alright, do we want to do this again?' It's like the first course. A nice low-key dinner, maybe a drink afterwards, and then that's perfect."

Joe's new relationship comes just three months after he revealed he's "very single" and just taking life in his stride following reports he was dating model Daiane Sodré.

He said at the time: "I'm very single, hanging out, enjoying life."

Joe's last serious relationship was with Gigi Hadid, 21, last year before she split with him and started Zayn Malik.
