Hemsworth and Hiddleston are currently filming Thor: Ragnarok together in Australia.When Hemsworth was asked about his co-star by Nova, an Australia radio station , the actor explained, "I've seen Tom around. He looks happy."Okay, we said we was a mediator, not a mind reader! The response is kind of weak, but it's probably all Hiddleston and Swift would allow Chris to say on the topic.The radio hosts also asked if Chris had met Swift herself. He revealed that he hadn't met her personally because "they only got here a few days ago," but added that she is "obviously hugely talented." If she does visit the set, Chris said he would ask her to play a couple tunes. "I'll just hand her the guitar in between set ups with the camera. I'll be like, 'Off you go.'"Now that I would like to see.Listen to the interview, below.
