Robert Downey Jr. Just Burned Tom Hiddleston With the Perfect Taylor Swift Joke

While it’s no big secret that Tony Stark and Loki are enemies in the Marvel universe, their real-life counterparts Robert Downey Jr. and Tom Hiddleston have a friendship that encourages camaraderie and even jest. Case in point? Downey Jr.’s good ol’ fashioned ribbing of Hiddleston’s very public romance with Taylor Swift.

Hiddleston joined Instagram on Tuesday, giving Hiddleswift countless opportunities to do it for the ‘Gram, and like any good friend, Downey Jr. welcomed him with an Instagram post of his own, slyly poking fun at the ubiquitous Hiddleswift headlines in a manner that would make Tony Stark proud.

The image that the Iron Man actor used was of Hiddleston wearing the infamous “I [heart] T.S.” shirt from Swift’s much-publicized 4th of July festivities, which Downey Jr. wryly captioned, “Join me in welcoming the biggest T. Stark fan of them all to Instagram! @twhiddleston”
