They might be on opposing sides in the Marvel movies, but in real life Loki and Iron Man are the best of pals.

Tom Hiddleston uploaded his very first Instagram photo on Tuesday of this week, showing off his fresh Loki garbs as filming began on Thor: Ragnarok, which will be out this year. https://www.instagram.com/p/BI464OMhT3E/ Lovely photo. Always nice to have Tom Hiddleston doing more acting work. The Night Manager was the best thing on television for a month and we reckon he'd make a great James Bond. Grand. It's always good to see your friend make the next great social media leap. And as we said earlier, Tom Hiddleston and Robert Downey Jr. are real life good pals. So much so that soon after Hiddleston's upload, Downey Jr. did what all good mates do - he took the mick out of his friend. https://www.instagram.com/p/BI53kgNgTZn/ In true Tony Stark fashion, Downey Jr. reminded us that Loki isn't such a terrifying chap, but instead rather a lovely young man who just likes to have a bit of fun with his lovely girlfriend Taylor Swift. "Join me in welcoming the biggest T. Stark fan of them all to Instagram! @twhiddleston" Downey Jr. wrote. Oh you boys... team up soon ok? Preferably before Avengers: Infinity War.
