The 35-year-old actor took to Comic-Con in San Diego, California, on Saturday in his first press event in America since spending time in Australia with new girlfriend Taylor Swift.
Swift, 26, accompanied the actor Down Under while he filmed Thor: Ragnarok – and a bunch of Hiddleswift sightings ensued. The two were spotted out on a romantic dinner at an Italian restaurant and Swift joined Hiddleston and his Avengers costars Chris Hemsworth and Mark Ruffalo for a private screening of Ghostbusters.

Hiddleston hit up Comic-Con without his leading lady, and joined his fellow Kong: Skull Island cast members in Hall H.
Conan O’Brien served as the presentation’s master of ceremonies.
