The man Taylor Swift once called “Mr. Casually Cruel” can dish it out, but can’t take it. Jonas tried to court Hadid from the time they met (he was 19 and she was, um, 13!), but the two didn’t actually date for six more years. When the relationship fizzled, he was peeved to see her hook up with Zayn Malik. Like an irate tween, the JoBro deleted a pic of himself with the One Directioner, then threw in a bit of shade for good measure. “I think it’s interesting that she moved on so quickly,” he said in an interview. “I mean, it was definitely quick.”
