Charlie Hunnam was all smiles when he greeted a group of excited fans in Northern Ireland on Sunday. The sexy star has been busy filming The Lost City of Z [8] in Belfast, and he's been spotted on set with Robert Pattinson [9], his handsome costar. This weekend's sweet fan interaction came when Charlie pulled up alongside a group of people, rolling down his window and waving from the backseat of a car.

The actor took some time to sign autographs and chat with everyone, and at one point, a fan showed off his tattoo of Jax Teller, Charlie's Sons of Anarchy character. Charlie definitely approved of the impressive ink, saying, "Solid tattoo, mate. Who did that tattoo? Fantastic job . . . Right on, man." Later, the tattooed fan tweeted his excitement [10], writing, "I just met Charlie Hunnam, showed him my JAX tattoo and he loved it! Got photos and autograph!!" He also shared a picture of the awesome ink [11], which depicts Charlie lighting up a cigarette as Jax.

Charlie's fun fan encounter came just a few days after his sexy V magazine spread [12] was revealed. In his interview with the publication, Charlie opened up about dropping out of the 50 Shades of Grey film [13], and he went shirtless for the must-see photo shoot, adding to his long list of hot moments [14] from over the years.
