Now this was a breakup I did not see coming.
And while I'd like to pretend this is a rumor, it is, in fact, real, which makes me sad. Why? Because these two were just so adorable together -- from their couple selfies to their date night at the Grammys to their secret handshake.
So let's break out the tissues and look back at 16 of Ariana and Big Sean's cutest couple moments.
We got our first glimpse of the two as a couple when they were spotted holding hands backstage at the 2014 MTV Video Music Awards.
