Robert Downey Jr. makes fun of Tom Hiddleston on Instagram

Just yesterday Tom Hiddleston signed up to Instagram and now Robert Downey Jr. has welcomed his Avengers co-star to the social network with a cheeky jibe.

Downey Jr. posted a picture of Hiddleston wearing that ‘I love T.S’ T-shirt (T.S being Taylor Swift) with the Iron Man actor jokingly making out that it refers to his character, Tony Stark. Check it out below:

“Join me in welcoming the biggest T. Stark fan of them all to Instagram,” he put in the caption. And so the banter begins! We can only hope that Hiddleston replies with a comeback.

Yesterday, he shared his first post with a photo of himself as Loki in Thor: Ragnarok:

The Marvel actor is returning to his role as Thor’s evil half-brother for the first time since 2013′s Thor: The Dark World.

And you can see him in action when Thor: Ragnarok is released on November 3, 2017.
