Robert Downey Jr. Welcomes Tom Hiddleston to Instagram with a Hiddleswift Joke

Tom Hiddleston is now on Instagram and he received a warm welcome to the social media app from his Marvel Universe co-star Robert Downey Jr.

The guys appeared together in the movie The Avengers and they’re both at work on upcoming films in the universe – Tom‘s Thor: Ragnorak as Loki and Robert‘s Spider-Man: Homecoming as Tony Stark/Iron Man.

Robert made a joke about Tom and his new girlfriend Taylor Swift in a post on Instagram. He shared a photo of Tom wearing a white tank top with “I [Heart] T.S.” written on it. The pic was taken during Taylor‘s Fourth of July weekend bash.

“Join me in welcoming the biggest T. Stark fan of them all to Instagram! @twhiddleston,” he captioned the pic.
