Robert Downey Jr. Makes Fun of Tom Hiddleston and Taylor Swift’s Whirlwind Romance

Tom Hiddleston finally embraced the 21st century yesterday and joined Instagram.

Because Hiddleston is brand new to Instagram, his friend and co-star Robert Downey Jr. decided to do him a favor and encourage his followers to follow the actor. But Downey couldn’t help but take the opportunity to poke a little fun at Hiddleston and his very public relationship with Taylor Swift.

Posting the paparazzi picture of Hiddleston wearing his “I <3 T.S.” shirt, Downey joked, “Join me in welcoming the biggest T. Stark fan of them all to Instagram!”

Hiddleston has yet to respond to Downey’s hilarious post, but we’re sure he appreciated the warm welcome.
