It's hard not to love Jamie Dornan.
While celebrating the premiere of his new film "Belfast," the actor got on stage at a post show party to serenade the crowd with his rendition of "Everlasting Love," a song made most famous by English band Love Affair in 1968.
The "Belfast" official site posted video of the impromptu performance, writing, "Jamie Dornan serenades the crowd at last night's #BELFAST premiere with his irresistible rendition of Everlasting Love."
In "Belfast," Jamie's character sings the song to Catriona Balfe's character. Catriona and fellow co-star Jude Hill can be seen dancing in the social media video.
According to Variety, Jamie was pulled up on stage to perform the song by the band at the afterparty. The band even stopped its set to welcome him onstage.

While chatting with ET Canada in September, Jamie joked that singing onscreen was "terror like you can't even imagine."
"I'm sure people heading into war are more terrified. It's rough. It's like an extra thing you have to worry about," he said, noting that Love Affair, who covered the song originally recorded by Robert Knight in 1967, helped bolster his vocals in the movie. "I'm not totally exposed by myself. I've sang in a lot of things recently."
"I think the last four, five things I've done I've sang in and it's becoming habitual," he added. "I don't remember how to just do straight acting and I'm always singing."
