Should we be worried about Joe Jonas? He's apparently not taking the news of ex-girlfriend Gigi Hadid shacking up with Zayn Malik very well — at least if his social media activities are any indication. (And I guess we now live in a world where they could be? Sure?)

Just as Hadid's new romance was starting to heat up, Jonas went and unfollowed her on Instagram — which, to be fair, makes sense. But he also unfollowed Malik, probably because the former One Direction member is likely to start posting photos of Hadid now that they've reached the hand-holding in public stage of their relationship.

And then — and then! — Jonas also deleted a photo from Twitter taken back in June of him with Malik and Kanye West hashtagged "squad." Guys? He really seems upset.
