The Welsh actor also treated fans to a Throwback Thursday snap with his co-stars from The Hobbit: The Battle of the Five Armies at Comic-Con in 2014.
"A Hobbit, a dwarf, a dragon, some elves and a bowman walk into a bar… #TBT," Evans captioned the photo featuring Cate Blanchett, Orlando Bloom, Elijah Wood, Benedict Cumberbatch, and Evangeline Lilly.
While Evans is currently shooting the thriller 10 x10 in Budapest, Hungary, rumors are swirling about a possible reconciliation with his ex-boyfriend, Jon Kortajarena.
The couple dated for two years and split in 2016.
Kortajarena reportedly posted and deleted photos from a recent Budapest trip on his Instagram Story on Sunday, along with a birthday message to Evans, who turned 38 a day earlier.
But when it comes to relationships, Evans prefers to keep his "private life" out of the headlines.
"I try to keep my personal life and my private life separate,' he recently told the U.K.'s Jackal Magazine. "Not for any reason other than there’s a clue in the title – it’s private. As an actor you have to keep some sort of enigma and mystery. There's a dignity to keeping private."
